classArgon2Digest : Hash

Argon2 Digest Wrapper implementing Hash interface.

This class adapts the Argon2 PHS to the generic Hash interface. The input data fed via update is treated as the password. Salt and other parameters must be provided at construction.

Note

Argon2 requires the length of the password to be known at the start of the hashing process.

Therefore, this implementation buffers the entire input provided via update calls until finish is called. This may consume significant memory for very large inputs.
