Hello, I'm trying to compare the results of the openssl tool with the cryptool 1.4.31
+ Filename topsecret.txt which only contains the character 'a' + Encrypt it with DES using CBC mode with key and iv = 0 produces the result '32ea a0fa 4f77 fb92' user@debian:~$ xxd topsecret.txt 0000000: 61 a user@debian:~$ openssl version OpenSSL 0.9.8o 01 Jun 2010 user@debian:~$ openssl enc -des-cbc -K 0 -iv 0 -nosalt -in topsecret.txt | xxd 0000000: 32ea a0fa 4f77 fb92 2...Ow.. user@debian:~$ + If I use the cryptool 1.4.31 to do the same exercise the result is '0C29 5D71 8258 D464' + I also noticed that openssl generates the same output for different modes of des e.g. user@debian:~$ openssl enc -des-ecb -K 0 -iv 0 -nosalt -in topsecret.txt | xxd 0000000: 32ea a0fa 4f77 fb92 2...Ow.. While if I do the same in Cryptool the output for the ECB mode is: '841B D8A4 2931 FCF5' Any ideas? thank you, Luis
