How do different hash algorithms compare?

Different hash algorithms vary in speed, security, and use cases. For example, SHA-256 is widely used for its security, while MD5 is faster but less secure.

What are the main differences between SHA-1 and SHA-256?

SHA-1 produces a 160-bit hash and is considered less secure due to vulnerabilities. SHA-256, part of the SHA-2 family, produces a 256-bit hash and is more secure.

Are there any use cases where MD5 is still acceptable?

MD5 can be used for checksums and non-security-critical applications, but it's not recommended for cryptographic purposes due to its vulnerabilities.

What about newer algorithms like SHA-3?

SHA-3 is the latest member of the Secure Hash Algorithm family, offering improved security and flexibility. It's designed to be resistant to various attack vectors.

Which hash algorithm should I use for password storage?

For password storage, it's best to use algorithms specifically designed for that purpose, like bcrypt or Argon2, as they include salting and are resistant to brute-force attacks.
