Weak Hashing Algorithm

MD5 and SHA1 are weak hashing algorithms and open to collision attacks. They are not suitable for cryptographic signature.

Remediation

At the time of writing, SHA3 is recommended. Best to use a slow hashing algorithm like bcrypt.
Ensure that the design allows one hashing algorithm to be replaced with another.
