SHA or MD5 Hash

Function calculating a SHA or MD5 digest hash

Evaluation

This expression evaluates to a function of the form:

(x) -> any

The function calculates the digest of argument x using the selected algorithm and returns it as a binary value or a hex string.

Processing

The returned function calculates the digest of argument x as follows:

• If x is nil, nil is returned.
• If x is of type binary the digest of its bytes is returned.
• If x is of type string the digest of the UTF-8 bytes of the string is returned.
• If x is of a type that can be cast to string - such as numeric types - it is cast to string and the digest of the UTF-8 bytes of the string is returned.
• If x cannot be cast to string, an error is thrown.
