Developer Documentation & Guidance

Practical developer scenarios, best practices, and common mistakes to avoid.

When Should I Use This Tool?

•Generating SHA-256 or SHA-512 digests for data integrity verification.
•Computing checksums for file downloads or API payload signatures.
•Generating HMAC message signatures for webhook payload verification.

Developer Best Practices

✓Use SHA-256 or SHA-512 for cryptographic digests and message signatures.
✓Never use MD5 or SHA-1 for security sensitive operations or password storage.
✓Use salted hashing algorithms (bcrypt, Argon2, PBKDF2) for user password storage.

Common Developer Mistakes

!Using fast cryptographic hash functions (SHA-256, MD5) for password storage.
!Omitting secret keys or random salts when verifying message signatures.
!Comparing hash outputs with non-constant-time string comparisons in security code.
