# title: Support for different hash algorithms in HASH system function
# decription:
# Test verifies only:
# 1) ability to use syntax: hash(<string> using <algo>)
# 2) non-equality of hash results for sha1, sha256 and sha512 using _TRIVIAL_ sample from ticket.
# build 4.0.0.713: OK, 1.094s.
#
# Note that for strings:
# '20177527e04e05d5e7b448c1ab2b872f86831d0b' and '20177527e04e05d5e7b448c1ab2b872f86831d0b'
# - current imlpementation of SHA1, SHA256 and SHA512 gives the same hash value.
# (See: https://stackoverflow.com/questions/3475648/sha1-collision-demo-example )
#
# NOTE. Since build 4.0.0.2180 (27.08.2020) we have to use *new* function for cryptograpic hashes
# when addition argument for algorithm is used: crypt_hash().
