Hi,
The function EVP_BytesToKey is used internally by this command (and
others) in order to create a key from a password. The iteration count is
set to 1. Look at the following link for more information :

How does passphrase "TEST" become
"key=033BD94B1168D7E4F0D644C3C95E35BF98D6BC98DA097F25270DEC053083AACF"?
How is it constructed? I've tried all supported hash functions (md5,
sha1, etc.), but they seem to produce different output.
Thanks a bunch in advance!
