Hello everybody and thank you all for reading. I'm doing some experiments with blowfish and triple DES ciphers. I'm encrypting some text files; using a password to generate the key and the IV; while using the "-p" option to let openssl show me the salt, the key and the IV onscreen.
As far as I've understood I could decrypt the output encrypted file just supplying the key and the IV. And actually if I do that, that is ALMOST what I get. But, the first eight characters of the source file didn't get decrypted, or at least they doesn't apparently get decoded correctly: I got a bunch of unreadable binary bytes instead. Here's what I did: $ openssl enc -bf -in source.txt -out encrypted -p enter bf-cbc encryption password: Verifying - enter bf-cbc encryption password: salt=FF01D744C268C056 key=22153E114FB3C2873BAE05873AFBD19C iv =F68A9A229A516752 Then if I try to decode the encrypted file with: openssl enc -d -bf -in encrypted -K 22153E114FB3C2873BAE05873AFBD19C -iv F68A9A229A516752 Then the output *of the first eight bytes* isn't even ASCII so I can't paste it here! The rest of the file is perfectly decrypted though. I tried with files of various length and they are all decrypted perfectly but the first chars. I tried with versions 0.9.8g (19 Oct 2007) and 0.9.8k (25 Mar 2009) with the same results. Using des3 in place of bf doesn't change that behaviour too. Please kindly help me to understand what I'm missing. Thank you SO much! -- Alfredo Belmonti ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager majord...@openssl.org
