RE: Error copiling ssl: undefined reference

[Jeremy Farrell]

It doesn't make any difference in this case, but you'd be best to get in the 
habit of putting the libraries last; for example
 
gcc cli.c -lssl -lcrypto
 
A few compilers only search libraries for references which they know about at 
the time the library is listed. If you were using that sort of compiler, you 
would still have your problem.

A lot of thanks, now roks perfectly.
The problem it was that i put the commnad line with -o and the correct 
form was:
gcc -lssl -lcrypto cli.c

Thanks.

Didn't realise anyone was using CFB for that. 


Note - there is now a Debian bug logged too for encfs which appears to be 
impacted by this change.


See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=571810

I've forwarded your email (SteveH) noting that you are reverting that change.

Thanks,
Tim.

There are no default algorithm implementations in the CryptoAPI ENGINE at
present: just private key operations. If you load a private key from the
CryptoAPI ENGINE the operations are transparently redirected.

Capi engine

Hello all !
How can I specify OpenSSL to use capi engine by default ???

interoperability of C++ libcrypto and Java bouncy castle

[ashuahen]

I am using AES_CBC with padding (using PKCS#5 to pad) on C++ side:

AES_set_encrypt_key( keyBuf, 128, &key )
keyBuf contains key string
key is the key generated

Block Lenght is 16

AES_cbc_encrypt (ibuf, obuf, lenpad, &key, iv, AES_ENCRYPT)
ibuf = input data
obuf = encrypted data
lenpad = length of data (input data length + pad data length)
key = key generated by AES_set_encrypt_key
iv = initialization vector

On java side:
I am decrypting using following:
 
SecretKey aesKey = new SecretKeySpec(KeSo.getKey(keyBuffer), "AES");
keyBuffer: is same as KeyBuf @ C++ side

Cipher cipherDec = Cipher.getInstance("AES/CBC/PKCS5Padding", "BC");
cipherDec.init(Cipher.DECRYPT_MODE, aesKey, iv); 
cipherDec.doFinal(enc);
enc: data to be encrypted in byte.

Problem
===

I was using libcrypto.0.9.8a and every thing was working fine.
But as a part of upgrade on Sun SPARC licrypto0.9.8a is changed to
libcrypto.0.9.8k and things became worst. Encryption is not giving any
problem but during decryption with the same code I am getting
BadPaddingException.

Please help me out, this problem has made my life hell.

Thanks
Ashutosh
