Enter abc and select SHA-256 to generate its digest.

Case, whitespace and line breaks change the hash. Hashing does not provide decryption back to the original text.

Hashes such as SHA-256 are used to compare content, not to recover plaintext. Recompute after transfer and compare with a trusted expected digest.

Plain SHA-256 is not an appropriate password-storage scheme; use a password KDF.
A digest only detects tampering when the expected value comes from a trusted source.
Record the algorithm name together with the digest.

A common use is comparing a downloaded ZIP SHA-256 with the publisher’s official checksum.
