getPasswordHashAlgorithm method

String getPasswordHashAlgorithm()

Gets the the hash algorithm used to protect the password value. Possible values are: Sha256, Sha384, Sha512.

return The hash algorithm used to protect the password value. Possible values are: Sha256, Sha384, Sha512. throws BiosealException An error has occurred during Bioseal Library execution.
