I am using OpenSSL version 1.1.1b (26 Feb 2019) to encrypt/decrypt files.
Everything is working fine but I am getting a Warning I do not understand.
openssl enc -d -aes-256-cbc -a -pass pass:$pwd -in $file *** WARNING : deprecated key derivation used. Using -iter or -pbkdf2 would be better.
Can anyone explain to me what is it about and how to solve it?
