FAQ
What's the difference between SHA-1, SHA-256, SHA-512?
SHA-1 produces 160-bit hash with known collision vulnerabilities. SHA-256 produces 256-bit hash, highly secure and widely used. SHA-512 produces 512-bit hash, highest security for demanding scenarios.
Which is more secure, SHA or MD5?
SHA family is much more secure than MD5. MD5 has serious collision vulnerabilities and is not suitable for security. SHA-256 and SHA-512 are recommended secure hash algorithms.
Can SHA-256 be used for password storage?
SHA-256 can be used for password storage with salt. Better choices are password-specific algorithms like Bcrypt or Argon2.
