Help, > The Openssl.org documentation states that “all block ciphers normally > use PKCS#5 padding”. This must be some mistake, PKCS#5 is for Password Base key Derivation Functions (PBKDF) - not for padding.

Salt is parameter for PBKDF but if you specified -K/-iv this will not be used because you provided all parameters (key_block and initialization_vector) to start encrypting in CBC mode. > Encrypted and Encoded Packet following > > 2yjq5YMovrE= > Length Encrypted Packet = 13 12, new line does not counts :-) Pay attention that this packet is base64 format. You must de-base64 on PC side (should be 8 bytes) and than try to decrypt. Depending on decryption mode, key_block and initialization_vector may be provided as parameters or may be generated using PKCS#5 PBKDF with require passphrase, salt and iteration count. Check this.
