CRC was never a cryptographic hash so there is no need to deprecate it. MD5 (and SHA1) is already absent or deprecated in many cryptography libraries, e.g. https://cryptography.io/en/latest/hazmat/primitives/cryptographic-hashes/#sha-1 https://cryptography.io/en/latest/hazmat/primitives/cryptogr...
