How this tool works

SHA-256 produces a fixed-length digest from input text.

It is useful for checksums and integrity comparisons, but password storage requires dedicated password hashing algorithms and salts.

Examples

  • Hash a sample payload for a test assertion.
  • Compare two pieces of text by checking their SHA-256 digests.

Common use cases

Integrity checks
Test fixtures
Digest comparisons
