My question is, if multiple servers are used, can this attack (and possibly others) be avoided? Example: initiate_server: TLS connect with client initiate_server: send encrypted data over TLS to client (including target_server:port) initiate server: TLS connect with target_server initiate_server: send encrypted data over TLS to target_server (including listen port, client, etc) client: attempt TLS connection to target_server:port target_server: accept TLS connection from client client/target_server: verify additional encrypted data (from initiate_server) to establish a connection If I understand this, you're trying to use 'initiate_server' to introduce the other two machines to each other, and relying on those two machines' server certificates to allow initiate_server to verify that it's talking to the right machine? Not exactly, I was trying to develop a method where the transaction could occur securely w/o a client certificate. I am beginning to believe that this is not possible. The original idea I had is starting to look like a twisted/reverse way that Kerberos does these things (I have implemented GSSAPI using host principles, which takes the need of the client cert out of the process). I see two problems with this. One is that initiate_server isn't authenticated to the other machines--- evil_server could connect to target_server, give it fake encrypted data and client info, and then impersonate the client. I was assuming that the clients (and servers) would have the "longer term" trust of the initiate_server via a PEM file that has it's identity. The other problem is that this isn't really avoiding having a certificate on the client machine. If you have a trustowrthy certificate on client, which initiate_server can use to authenticate the connection, why not use that certificate as a client certificate when client connects to target_server (and eliminate the role of initiate_server entirely)? Yeah, I wish I did not need to manage the client certificates. I am interested in setting up a local CA for client certs. One of my stumbling blocks is how to manage the install of a new client with libssl.so, but not openssl installed (so openssl req not there). Apologies if I don't understand your original motivation, but I don't see how the introducer scheme helps you any. If my understanding is up to speed you need to manage client certs to do this right. Which brings me to my next set of questions about how to manage this from install to revocation. Having an app that can use certs, it appears, is nothing compared with how to deploy it and manage those certs ;) __ OpenSSL Project http://www.openssl.org User Support Mailing Listopenssl-users@openssl.org Automated List Manager majord...@openssl.org -- Mr. Kristen J.

This leads to a MiTM attack, where the mitm can impersonate the client because the server has not verified the client. Your understanding is flawed - while in the scenario you mention there is no binding of a client identity to a public key, SSLv3/TLS are not vulnerable to MITM - no third party can manipulate the stream without being detected. Yes, thank you. Upon further investigation I find that not using client certs means that the server cannot prove the identity of the client. So I think that the attack I am looking at is more of a client impersonation, where a rouge client pretends to be the real client. All it takes (I think) is for the rouge client to have enough information about the server (e.g. our application installed) and be able to present itself to the server as the client under attack. Since the server cannot distinguish, then the rouge client could use our application to manipulate the server. It seems that the only way to help prevent this is to use client certificates to prove the identity of the client. The problem I am having with this is that managing certs for a few servers is easy, while managing it for 1000's of clients is not. I'm looking for the way around this and still keep things secure, but maybe there is not? __ OpenSSL Project http://www.openssl.org User Support Mailing Listopenssl-users@openssl.org Automated List Manager majord...@openssl.org -- Mr. Kristen J.

Is there an alternate way to do AES key wrap using the nightly OpenSSL in FIPS
mode?
More to the point: Is the FIPS module limited to a subset of the FIPS
approved modes of operation?
Can it do the NIST specified (badly designed!) key wrap mode, which
unnecessarily helps attackers by including a MAC of the wrapped key?
Can it do traditional modes (ECB, CBC, CFB, OFB)?
Can it do the new FIPS modes (CTR, GCM)?
Can it do the various modes from the modes workshop days (ABC, XCBC,
the flawed CBC-MAC etc.)?
Can the key and/or IV be set directly?
Can the key and/or IV be set to the output of an approved RNG?
Can the key and/or IV be set from a decrypted wrapped key?
Can the key and/or IV be set from the output of an approved hash algorithm?
Can the key and/or IV be set from one of the approved DH variants, with
all of
the parametric variations permitted?

Truncate the string to your desired file name length, but not so short that accidental collisions become likely (Example to keep up to 16000 file names likely different, use file names with 2 * log2(16000)=2*14=28 bits minimum). Where can I learn more about this formula? I think it does not work well for small number of files and I wonder why it isn't something like "log2(n)+20" or "2*log2(n)+10" or so? Google "Birthday paradox", the formula I gave is a rough and not very precise variant. __ OpenSSL Project http://www.openssl.org User Support Mailing Listopenssl-users@openssl.org Automated List Manager majord...@openssl.org

openssl failing to download remote certificate
I tried openssl to download a remote cert on my181.svr.us.cyber.net Below are the 3 steps to generate self sign certificate. 1)To generate keys: /opt/boksm/lib/openssl genrsa -des3 -out server2.key 2048 -config /usr/sfw/lib/webmin/acl/openssl.cnf 2)To generate CSR /opt/boksm/lib/openssl req -new -key server2.key -out server2.csr -config /usr/sfw/lib/webmin/acl/openssl.cnf 3)To generate certificate view plaincopy to clipboardprint? /opt/boksm/lib/openssl x509 -req -days 365 -in server2.csr -signkey server2.key -out server2.crt /opt/boksm/lib/openssl x509 -req -days 365 -in server2.csr -signkey server2.key -out server2.crt And then used view plaincopy to clipboardprint? /opt/boksm/lib/openssl s_client -connect my181.svr.us.cyber.net:12201 -key server2.key -cert server2.crt -CAfile ca.crt /opt/boksm/lib/openssl s_client -connect my181.svr.us.cyber.net:12201 -key server2.key -cert server2.crt -CAfile ca.crt To connect view plaincopy to clipboardprint? /opt/boksm/lib/openssl s_client -connect my181.svr.us.cyber.net:12201 -key server2.key -cert server2.crt -CAfile ca.crt /opt/boksm/lib/openssl s_client -connect my181.svr.us.cyber.net:12201 -key server2.key -cert server2.crt -CAfile ca.crt view plaincopy to clipboardprint?
