I'm trying to encrypt a file using DES in CBC mode but when I try to specify the key derivation function it tells me my command is wrong. It only fails when I try specify the KDF and works when I don't. This is the command i'm trying to use - openssl enc -des-cbc -pbkdf2 -in test.txt -out test.bin -pass pass:test
This command is taken directly from my reference so why does it not pick up the KDF? Is it because i'm using the wrong version of openssl (LibreSSL 2.6.4) or do I have to manually add pbkdf2? If so how do I?
