Let’s calculate similarity of pairs in a signature matrix like this : WebHash algorithms ¶ There is one constructor method named for each type of hash. All return a hash object with the same simple interface. For example: use sha256 () to create a SHA-256 hash object. You can now feed this object with bytes-like objects (normally bytes) using the update () method.

WebOn observation this looks like base64 encoding (note this isn't a hash, it's an encoded string). I can tell this as I know that in base64, one pads the end of the string with = as necessary to give the base64 string a predictable length. Other tell-tale signs can be from the usage of certain characters in the string.
