Secure Hash Technique, or SHA, is a cryptographic hashing algorithm used to assess the reliability of a specific piece of data.The Secure Hash Algorithm, or SHA, family of algorithms includes the SHA 256 algorithm. The NSA and NIST collaborated to publish it in 2001 as a replacement for the SHA 1 family, which was gradually becoming less resistant to brute force attacks.
The 256 in the name refers to the final hash digest value, meaning that regardless of the amount of plaintext or cleartext present, the hash value will always be 256 bits. The other SHA family algorithms are somewhat comparable to SHA 256. SHA 256 is the best to secure your information. The SHA256 hash function generator creates a SHA256 hash (SHA256 Encode), which can be used as a secure 64-character password or as a key to secure sensitive information like financial transactions and personal information.
