# 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.
