I think you will get less-cryptic error messages if you put a call to ERR_load_crypto_strings() near the beginning of your program: http://www.openssl.org/docs/crypto/ERR_load_crypto_strings.html Alternatively, you can look up what reason #109 is in your headers (I think it's EVP_R_WRONG_FINAL_BLOCK_LENGTH), or look at line 323 of your version of evp.c to see what error condition it's testing there. As for your actual error, I don't know the cause, but I notice you're giving zero bytes of input to the decryption function--- this may make some padding modes unhappy: http://en.wikipedia.org/wiki/Padding_(cryptography)#CBC_mode ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager majord...@openssl.org
