Methods

SetHashAlgorithm

procedure SetHashAlgorithm(algorithm: Option)

Sets the cryptographic hash algorithm to use for subsequent calls to ComputeHash().

Parameters / Return Value

  • algorithm Option

    Option

MD5

procedure MD5(): Integer

The MD5 message-digest algorithm is a widely used hash function producing a 128-bit hash value. Although MD5 was initially designed to be used as a cryptographic hash function, it has been found to suffer from extensive vulnerabilities. It can still be used as a checksum to verify data integrity, but only against unintentional corruption. It remains suitable for other non-cryptographic purposes, for example for determining the partition for a particular key in a partitioned database. See https://en.wikipedia.org/wiki/MD5

Parameters / Return Value

  • Returns Integer

    Integer

SHA1

procedure SHA1(): Integer

In cryptography, SHA-1 (Secure Hash Algorithm 1) is a cryptographic hash function which takes an input and produces a 160-bit (20-byte) hash value known as a message digest – typically rendered as a hexadecimal number, 40 digits long. It was designed by the United States National Security Agency, and is a U.S. Federal Information Processing Standard Since 2005 SHA-1 has not been considered secure against well-funded opponents,and since 2010 many organizations have recommended its replacement. See https://en.wikipedia.org/wiki/SHA-1

Parameters / Return Value

  • Returns Integer

    Integer

SHA256

procedure SHA256(): Integer

Contained in SHA-2 (Secure Hash Algorithm 2). SHA-2 is a set of cryptographic hash functions designed by the United States National Security Agency (NSA). They are built using the Merkle–Damgård structure, from a one-way compression function itself built using the Davies–Meyer structure from a (classified) specialized block cipher. SHA-2 includes significant changes from its predecessor, SHA-1. SHA-256 and SHA-512 are novel hash functions computed with 32-bit and 64-bit words, respectively. They use different shift amounts and additive constants, but their structures are otherwise virtually identical, differing only in the number of rounds. See https://en.wikipedia.org/wiki/SHA-2

Parameters / Return Value
