[openssl-users] Password based key derivation

Any help on following questions is appreciated.

 1)      Can the function PKCS5_PBKDF2_HMAC_SHA1() in 0.9.8zf be used to derive a key for AES-256-CBC encryption from user supplied passphrase?


2)     Is PKCS5_PBKDF2_HMAC_SHA1() preferable to EVP_BytesToKey()  and why ? I see PKCS5_PBKDF2_HMAC_SHA1() uses HMACs and is part of standard.


On debugging, could see PKCS5_PBKDF2_HMAC_SHA1() working with 256-bit key but after returning from the function, the data in the stack frame gets corrupted for me and overwrites few other parameters leading to Seg Fault.


Thank you,
