Popular Hashing Algorithms
Several hashing algorithms have been developed over time, with varying levels of security and performance. The most notable ones include:
-
MD5 (Message Digest Algorithm 5):
- Developed in 1992, MD5 produces a 128-bit hash value.
- Widely used in the past but is now considered insecure due to vulnerabilities that allow collision attacks.
-
SHA (Secure Hash Algorithm):
- SHA-1: Produces a 160-bit hash value but is no longer considered secure due to collision vulnerabilities.
- SHA-2: A family of hash functions (e.g., SHA-224, SHA-256, SHA-384, and SHA-512) that are highly secure and widely used in modern cryptography.
- SHA-3: Introduced in 2015, SHA-3 is based on a different design (Keccak algorithm) and offers robust security.
-
BLAKE2 and BLAKE3:
- Fast and secure hash functions designed for high-performance applications.
-
Argon2:
- Specifically designed for password hashing, offering resistance against brute-force attacks.
