C# and openssl problem

[george r smith]

Help all,   I am trying to use an openssl script on an AIX box to produce and encrypted packet. This packet will have to be decrypted by a C# program. I am having any luck in getting the C# program to decrypt the packet encrypted by the AIX script.   The Openssl.org documentation states that “all block ciphers normally use PKCS#5 padding”. The options that I have in C# are ANSIX923,ISO10126,NONE,PKCS7,ZEROS. Is this my problem. Can I change the default padding in openssl.   Any code anyone has that can help me do this roundtrip between openssl and C# would be appreciated.   Below are my scripts, the successfull decryption was done of course by the openssl script not a C# program..   thanks grs     echo HELLO|openssl enc -a -salt -S 3031323334353637 -iv 31464F4C4C455431 -des3 - K 31323334466F6C6C657426265472696D6461746131323334 -out flnk_encrypt/grs_encrypt.txt   Encrypted and Encoded Packet following 2yjq5YMovrE=   Length Encrypted Packet = 13   openssl enc -d -a -salt -S 3031323334353637 -iv 31464F4C4C455431 -des3 -K 313233 34466F6C6C657426265472696D6461746131323334 -in flnk_encrypt/grs_encrypt.txt 2yjq5YMovrE=   Packet was decrypted to following HELLO   Length Decrypted Packet = 6 X.PKT        = HELLO Length X.PKT = 5
