What is sha256?

SHA-256 or Secure Hash Algorithm 2 is one of several cryptographic hash functions that takes input and produces a 256-bit (32-byte) hash value. This message digest is usually then rendered as a hexadecimal number which is 64 digits long.

SHA-256 is most often used to verify that a file has been unaltered. This is done by producing a checksum before the file has been transmitted, and then again once it reaches its destination.

The SHA256 hash is NOT encryption. This is just a fingerprint of this entry. However, this is a one-way transaction, and therefore it is almost impossible to reverse the SHA256 hash to get the original string. SHA256 hash is composed of 64 hexadecimal characters. Enter a word or some text in the sha256 online form above to know the corresponding SHA256 hash.
