Cryptographic Hashing & Data Integrity Verification
Hashing feeds your input into a one-way cryptographic algorithm (such as SHA-256 or MD5) to produce a fixed-length hexadecimal digest. The slightest change in input text dramatically alters the resulting hash (the avalanche effect). Use these digests to verify file integrity, generate checksums, or compare data fingerprints without exposing the underlying text.

Technical Reference & Standards
Passwords need slow hashes
SHA-256 is fast and inappropriate for password storage alone. Prefer bcrypt, scrypt, or Argon2 from dedicated tools when storing credentials.
Common Use Cases
- Verify downloads against published checksums
- Fingerprint config files in support tickets
- Teach integrity concepts before introducing HMAC
- Compare outputs with MD5 when legacy systems require migration planning

Frequently Asked Questions
- Is SHA-256 the same as encryption?
- No. Hashing produces a fixed-length digest you cannot decrypt back to the original. Encryption is reversible with the correct key.
- Hex vs Base64 output?
- Same bits, different encoding. APIs may expect lowercase hex while others expect Base64—match your verifier’s format.
