Hashing functions

Several hashing functions for sequences of characters or bytes are available.

MD5

Return MD5 hash for a string.

string Energy.Base.Hash.MD5(string text, Encoding encoding)

string Energy.Base.Hash.MD5(string text)

SHA-1

Return SHA-1 hash for a string.

string Energy.Base.Hash.SHA1(string text, Encoding encoding)

string Energy.Base.Hash.SHA1(string text)

SHA-256

Return SHA-256 (SHA-2) hash for a string.

string Energy.Base.Hash.SHA256(string text, Encoding encoding)

string Energy.Base.Hash.SHA256(string text)

SHA-384

Return SHA-384 (SHA-2) hash for a string.

string Energy.Base.Hash.SHA384(string text, Encoding encoding)

string Energy.Base.Hash.SHA384(string text)

SHA-512

Return SHA-512 (SHA-2) hash for a string.

string Energy.Base.Hash.SHA512(string text, Encoding encoding)

string Energy.Base.Hash.SHA512(string text)

CRC

For each characters do a 5-bit left circular shift and XOR in character numeric value (CRC variant).

string Energy.Base.Hash.CRC(string value)

string Energy.Base.Hash.CRC2(string value)

CRC-16-CCITT

Calculate 16-bit CRC-CCITT checksum with specified polynominal and initial value.

ushort Energy.Base.Hash.CRC16CCITT(byte[] array, ushort poly, ushort init)

ushort Energy.Base.Hash.CRC16CCITT(string text, ushort poly, ushort init)

PJW

For each characters add character numeric value and left shift by 4 bits (PJW hash).

uint Energy.Base.Hash.PJW(string value)
