revoking the OCSP responder certificate
Hi everyone, I just revoked the OCSP responder certificate as you can see: file index.txt -- R 040530223109Z 030605151409Z 03 unknown /C=ES/ST=Andalusia/L=Seville/O=Mazinger Z inc./OU=pepe/CN=OCSP responder prueba 2/emailAddress=ocsp - end of index.txt - openssl ocsp -index private/index.txt -port 8890 -CA private/cacert.crt -rsigner certs/3.crt -rkey key/3.key -text -out log.txt certs/3.crt is the file which contents the certificate and key/3.key contents the private key. It still works as OCSP responder whether it even returned info about its status (revoked). What shall I do if I want to revoke the OCSP responder certificate? by using a CRL?

Re: Minimum RSA Key length ?
Dear John- I have used 1024 certs on my test 2k server for SSL connections to a browser, no problem. Encryption confirmed with a pacekt sniffer. As PK encryption is a hybrid, the use of resource intensive Asymmetric encryption (RSA or DH public key) is reserved for securely exchanging the 128 bit session key so that the connection can then use resource efficient symmetric encryption (3des, CAST5, IDEA, AES, TwoFish) for the data transmission. Since the certificate is used solely for authentication and session key exchange, its size is not a factor except in high volume sites where it may be a drag on responses. If volume was not a major consideration, and data security was...I would use a large key and better symmetric algorithms for things like a IPSec VPN, a lite VPN through SSL, or http over SSL. As I said, the literature by respected cryptographers supposes that 1024 bit asymmetric/90 bit symmetric keys are in danger or have been broken by now. The Bernstein paper suggests a work reduction of those suppositions by 1/3. So , if he is correct (jury is out but no major flaws found) a 1024 bit cert is really about 683 bits in effective strength. That would give you the session key for that particular SSL session and decrypt it. Who and why anyone would want to do that depends on your threat model. Anyway, the proof of the pudding is in the eating. Can you point me to a secure site that uses a key size 1024 bits? I can't find one for love nor money. Why commercial CAs don't issue larger certs may be the volume/work load factor. Maybe its business, larger one's now would be an admission that 1024 bits are compromised. I know Thawte will trigger and sign 2048 bit personal certificates created in a Mozilla browser. But in any case, you can create a server certificate of any size using OpenSSL. The benefit of going with a commercial CA is that they are listed in the Root Stores of the browsers. However, adding a Root cert to those stores is very easy. If you can securely distribute a Root (either out of channel or get visitors to your site to install them), then you can offer a better level of security for the data exchanged over SSL.

Re: Blinding Breaks Engines?
Here is an email I sent to the list back in March regarding what I think is the
same issue (this was entered into the bug database though, I don't know the bug
number). Basically, I saw the same issue with the ESA Blinding patch when
using a Broadcom card (engine ubsec). If I backed out the patch then the
problem went away. However, I was using 0.9.7a, which did not contain the
patch so it was easy to back out, just don't apply it.
I thought the issue was fixed with the version of the RSA Blinding patch that
worked in multithreaded environments, which I think is what's in 0.9.7b.
However, I have not actually tried 0.9.7b.

Subject: Crash with openssl and ubsec and RSA blinding patch (CAN-2003-0147)
To: [EMAIL PROTECTED]
Hi,
I'm using openssl 0.9.7a with a Broadcom accelerator card (engine type
ubsec).
If I apply the patches to rsa_eay.c and rsa_lib.c which fix CAN-2003-0147,
and
then try and create an RSA key and CSR at the command line while using the
Broadcom card then openssl crashes. The command is:
openssl req -engine ubsec -newkey rsa:1024 -sha1 -keyout foo.pem -out
foo.csr
(I use foobar for the password, CN, etc., doesn't matter for the test.)
Doing:
openssl req -newkey rsa:1024 -sha1 -keyout foo.pem -out foo.csr
does not crash.
Similarly, building openssl without the patches avoids the crash, even when
using -engine ubsec.
After some poking around there is a suspicous looking line of code in
hw_ubsec.c:ubsec_mod_exp() (which gets called eventually by the blinding
code),
here's part of that function:
/* Check if hardware can't handle this argument. */
y_len = BN_num_bits(m);
if (y_len max_key_len) {
UBSECerr(UBSEC_F_UBSEC_MOD_EXP, UBSEC_R_SIZE_TOO_LARGE_OR_TOO_SMALL);
return BN_mod_exp(r, a, p, m, ctx);
}
if(!bn_wexpand(r, m-top))
{
UBSECerr(UBSEC_F_UBSEC_MOD_EXP, UBSEC_R_BN_EXPAND_FAIL);
return 0;
}
memset(r-d, 0, BN_num_bytes(m)); /* IS THIS RIGHT ??? */
if ((fd = p_UBSEC_ubsec_open(UBSEC_KEY_DEVICE_NAME)) = 0) {
fd = 0;
UBSECerr(UBSEC_F_UBSEC_INIT, UBSEC_R_UNIT_FAILURE);
return BN_mod_exp(r, a, p, m, ctx);
}
if (p_UBSEC_rsa_mod_exp_ioctl(fd, (unsigned char *)a-d, BN_num_bits(a),
(unsigned char *)m-d, BN_num_bits(m), (unsigned char *)p-d,
BN_num_bits(p), (unsigned char *)r-d, y_len) != 0)
{
UBSECerr(UBSEC_F_UBSEC_MOD_EXP, UBSEC_R_REQUEST_FAILED);
p_UBSEC_ubsec_close(fd);
return BN_mod_exp(r, a, p, m, ctx);
}
Coming into this function from the blinding code the arguments r and a
are
the same BIGNUM. If r is zeroed then when the BN_num_bits(a) call is made
a
few lines later there is a problem since a is now zero.
I don't know the BIGNUM stuff, but this seems suspicious. And removing this
line of code fixes the problem. Maybe someone who knows this stuff better
can
say if it seems ok?

RE: differentiate incoming data
Hi everyone,
when BIO_puts writes data after a handshake, is the data encrypted during
the send?
Yes. You *can't* send unencrypted data over an SSL connection (unless you
negotiate a null cipher).
I want to write a server to run to accept data from one
connection(insecure) and encrypt it and send it to a process waiting on
another server and from there decrypt it and send it to another
process(port forwarding?) Now in that case each of the two servers will
need to accept data from two sources and also depending on which source
the data appears to come from needs to encrypt/decrypt data and send it
accordingly.
Okay.
How can i differentiate between encrypted and unencrypted
data. or can i identify sources from the data hearders? What are the
api's i can use.
You're writing the server, so you should know which connection is which.
You can keep, for each connection, a flag indicating whether it's encrypted
or not and a pointer to the associated peer connection.
also which api's can be used to write/read such data.?
For encrypted data, just use the OpenSSL APIs. For unencrypted data, use
the normal network APIs.
Your question is one of those questions where what you're trying to do is
so simple that there's no way in general to answer your question to your
satisfaction. I have no idea what part of the problem you're having
difficulty with.
As you described things, if you make the connection outbound, it's SSL. If
you received the connection inbound, it's plaintext. So just keep track.
Maybe:
typedef struct
{
int peer_fd;
SSL *ssl;
} connection;
Just use an array of these indexed off the file descriptor. You can use a
'peer_fd' of -1 to indicate inactive and you can use an 'ssl' of NULL to
indicate an unencrypted connection.
If you need to *receive* both SSL and plaintext connections inbound, the
simplest solution is to use two different ports.

Any ideas out there? the Common Name of your server certificate should be the FDQN, so it should be ragnarock.domain.tld and not ragnarock, that's why you got that warning message. Also since this service runs on a virtual server, should I have the virtual server under a different name then the actual server name? This is a single purpose server only.

Error reading Cert X509_V_ERR_CERT_SIGNATURE_FAILURE
hi,
I exported thawte server CA and verisign class3
certificates from the browser for testing and
converted to C structure using x509 -C -in xxx.cer
xxx.C and added to my SSL client. Following is the
code below.
I am calling this function in a loop to load the
certificates:
unsigned char thawte_cert[791] = {
0x30,0x82...};
unsigned char verisign_cert[576] = {
0x30,0x82...};
SSL_load_cert(ctx,thawte_cert,791);
SSL_load_cert(ctx,verisign_cert,576);
SSL_load_cert(SSL_CTX *ctx,char *c,int size)
{
x = d2i_X509(NULL,c,size);
cert_store = SSL_CTX_get_cert_store(ctx);
X509_STORE_add_cert(cert_store,x);
return;
}
I verified the same certificates in .pem format using
openssl s_client and its connects to
www.paypal.com..but when i connect from my client it
gives X509_V_ERR_CERT_SIGNATURE_FAILURE.
If i try connecting to www.thwate.com:443 it works but
it gives the same error when i am trying to connect to
other servers with thawte signed certificates.
Can anyone plese let me know what's going on
regards,
raj

Alternatively since I'm feeling in a good mood I'll say its probably a missing

For info. MSIE6 xenroll problems. Solved.
Not strictly openssl related but posted here anyway. If anyone can recommend a better place to post this, I would appreciate it. Around the middle of May a number of my users started being unable to apply for certificates from my web based certificate authority using MSIE6. I duplicated this with MSIE6sp1 on Windows2000 and could find no apparent reason. The xenroll would not instanciate in IE no matter what I tried (even the simple example from the MS devnet site). Having had similar problems before, I suspected that it could be a problem with the xenroll itself. As I could not find anything specifically refering to new problems, I resorted to installing likely patches. One of the following patches corrected the problems on my MS PC: 811630 818529 329115 323172 Any users having problems applying for user certificates using the Microsoft xenroll who are using Microsoft Internet Explorer version 6 should be advised that it may not work without upgrading the client with the above critical Microsoft patches available from: http://windowsupdate.microsoft.com/ -- Andy Brady Email : [EMAIL PROTECTED] Web Services GroupTel : +44(0)118 9499252 E.C.M.W.F.Fax : +44(0)118 9869450 Shinfield Park, Reading, RG2 9AX Web : http://www.ecmwf.int/ __ OpenSSL Project http://www.openssl.org User Support Mailing List[EMAIL PROTECTED] Automated List Manager [EMAIL PROTECTED]

I have defined SSL_library_init rather then

I have turned on DES,RC4 in chipers and MD5,SHA in

Could you let me know what could be problem.
I can connect to www.thawte.com and X509_verify

For Ex: www.google.com:443 i cannot connect,

Re: Error reading Cert X509_V_ERR_CERT_SIGNATURE_FAILURE
Hi Dr Steve, Since its an embedded platform it does not have debug or a serial interface. But i did debug further and found that OBJ_obj2nid returning 7 (RSA-md2) incase of www.google.com and it returns 8 (RSA-md5) incase of thawte.com. Basically its failing in EVP_get_digestbyname() UNKNOWN_MESSAGE_DIGEST_ALGORITH. I have disabled MD2 switch. But looking at the certificate below, both the server certificates use RSA-MD5.I dont understand why its returning RSA-md2.
