# Please note:
# 1) The collation of the password is irrelevant, the encryption uses
# the binary representation of the string without charset/collation.
# 2) These tests can not print the encoded text directly, because it's binary,
# and doing this would cause problems with source control.
# Instead, an md5() checksum is used, to verify the result indirectly.
# 3) Each md5() result must be identical.
# 4) The md5() result must never change, and must be stable across releases.
