Quick Answer
SHA-1 produces a 160-bit (40 hex character) hash. While deprecated for security, it's still used in Git for commit identification and some legacy systems.

Hash Generator
Generate MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes
About Hash Functions
MD5: 128-bit, fast but not secure for cryptographic use
SHA-1: 160-bit, deprecated for security-critical applications
SHA-256: 256-bit, widely used and secure
SHA-384: 384-bit, truncated version of SHA-512
SHA-512: 512-bit, most secure option

Supported Hash Algorithms
MD5 (Message Digest 5)
- Output size: 128 bits (32 hex characters)
- Speed: Very fast
- Security: Not recommended for security purposes
- Use cases: Checksums, file verification, legacy systems
SHA-1 (Secure Hash Algorithm 1)
- Output size: 160 bits (40 hex characters)
- Speed: Fast
- Security: Deprecated for cryptographic use
- Use cases: Git commits, legacy compatibility
SHA-256 (Secure Hash Algorithm 256)
- Output size: 256 bits (64 hex characters)
- Speed: Moderate
- Security: Considered secure
- Use cases: Digital signatures, SSL certificates, Bitcoin
SHA-384
- Output size: 384 bits (96 hex characters)
- Speed: Similar to SHA-512
- Security: Considered secure
- Use cases: Government and financial applications
SHA-512
- Output size: 512 bits (128 hex characters)
- Speed: Slower
- Security: Highest security margin
- Use cases: High-security applications, password hashing base
Common Use Cases
| Use Case | Recommended Hash |
|---|---|
| File integrity check | SHA-256 or MD5 |
| Password hashing base | SHA-512 (with salt + iterations) |
| Digital signatures | SHA-256 |
| Git commits | SHA-1 (legacy) |
| Blockchain | SHA-256 |
| API request signing | SHA-256 |
Security Notes
- Never use MD5 or SHA-1 for password storage - Use bcrypt, Argon2, or PBKDF2
- Always salt your hashes when used for passwords
- SHA-256 is the minimum for security-critical applications
- Same input = same output - Hashes are deterministic
