Cryptographic Hash Algorithm Specification Table
| Algorithm | Output Size | Security Status | Recommended Use Case |
|---|---|---|---|
SHA-1 | 160 bits (40 hex chars) | ⚠️ Deprecated | Legacy systems & Git commit digests |
SHA-256 | 256 bits (64 hex chars) | ✅ Recommended | TLS certificates, JWT signatures, API tokens |
SHA-384 | 384 bits (96 hex chars) | ✅ Secure | High-security financial & government apps |
SHA-512 | 512 bits (128 hex chars) | ✅ Secure | Digital signatures & high-entropy verification |
Frequently Asked Questions
What is a cryptographic hash function?
A cryptographic hash function converts input data of any size into a fixed-length hexadecimal digest (e.g., SHA-256 produces 64 hex characters). It is deterministic, one-way, and collision-resistant.
Is plain SHA-256 safe for password hashing?
No. Plain SHA-256 is too fast and susceptible to brute-force or rainbow table attacks. Use purpose-built, salted password hashing algorithms like bcrypt, scrypt, or Argon2.
Why is MD5 missing from the browser tool?
MD5 is cryptographically broken and omitted from the modern browser Web Crypto API (crypto.subtle). If you require MD5 for legacy file checksums, use the Yurlie backend REST API.
Is my sensitive data sent to any server when hashing?
No. All hash calculations are executed entirely inside your browser using the native Web Crypto API (crypto.subtle.digest). Your input data never leaves your device.
