Summary
The SHA-256 algorithm generates an almost unique, fixed-size 256-bit (32-byte) hash. This is a one-way function, so the result cannot be decrypted back to the original value.
Currently, SHA-2 hashing is widely used, as it is considered the most secure hashing algorithm in the cryptographic arena.
