Parameters str The input string raw_output If the optional raw_output is set to TRUE, then the sha1 digest is instead returned in raw binary format with a length of 20, otherwise the returned value is a 40-character hexadecimal number
- Secure Hash Algorithm - Wikipedia
Con il termine SHA (acronimo dell'inglese Secure Hash Algorithm) si indica una famiglia di cinque diverse funzioni crittografiche di hash sviluppate a partire dal 1993 dalla National Security Agency (NSA) e pubblicate dal NIST come standard federale dal governo degli USA ( FIPS PUB 180-4) Come ogni algoritmo di hash, l'SHA produce un message digest, o "impronta del messaggio", di lunghezza
- SHA-1 Cryptographic Hash Algorithm implemented in . . .
SHA-1 Cryptographic Hash Algorithm A cryptographic hash (sometimes called ‘digest’) is a kind of ‘signature’ for a text or a data file SHA1 generates an almost-unique 160-bit (20-byte) signature for a text There is a good description on Wikipedia; see below for the source code
- How to hash data with salt (C# | VB. NET) | Obviex
Description These code samples demonstrate how to hash data and verify hashes It supports several hashing algorithms To help reduce the risk of dictionary attacks, the code prepends random bytes (so-called salt) to the original plain text before generating hashes and appends them to the generated ciphertext (original salt value will be needed for hash verification)
