About the SHA1 Hash Generator

SHA-1 produces a 160-bit hash. Like MD5, it appears in older toolchains and git history contexts, but it is deprecated for security-sensitive collision resistance. Use this generator when a workflow specifically requires SHA-1.

How to use

  1. Paste the text to hash.
  2. Generate the SHA-1 digest.
  3. Use it only where SHA-1 is explicitly required.

Guidance

  • For new integrity checks, prefer SHA-256 or stronger.
  • For passwords, never store raw SHA-1 hashes.
  • Document algorithm + encoding whenever you publish a checksum.

FAQ

Is git still using SHA-1? Git historically used SHA-1 for object IDs; the ecosystem has been moving toward stronger transitions. App password hashing is a separate concern — do not copy git’s legacy choice into auth systems.
