Martin: The buffer that you give to the AES encrypt algorithm must be
evenly divisible by 16. Since data may be any size you add padding to
get to a 16 byte boundary. If your data happens to be evenly divisible
by 16, you add an extra 16 bytes (so that padding always exists). It is
common to se

I have a server built using OpenSSL and a Java client that uses PureTLS. On
occassions I see a very long delay (> 5 mins) between Client Hello (the
server returns an ack to the clientHello almost immediately) and the Server
Hello. What could cause this long delay? I have Ethereal traces if anyone

Seems like that's what it will do.

Thanks for the examples. :-)

But how will I know how big the Buffer
A) must be before encryption
B) and will be filled after encryption?

Hello Marek,
can you help me a little bit more how to handle AES with OpenSSL?
1. If I want to encrypt with AES_cbc_encrypt() I have to give the key I have
created with AES_set_encrypt_key(). For decryption vice versa?
2. What is the parameter "ivec" in AES_cbc_encrypt? What must set if I want

I think that:

Hello Mailinglist,
1. How must I init Openssl? Must I call additional init functions than this?
OpenSSL_add_all_algorithms();
OpenSSL_add_all_ciphers();
OpenSSL_add_all_digests();
ERR_load_crypto_strings(); // Only for debugging, right?
2. I found in openssl/aes.h the function AES_cbc_encrypt() b
