Hash Algorithm Knowledge:
MD5 (Message Digest Algorithm 5)
Generates 128-bit (16-byte) hash values. First-generation hash algorithm designed by Ron Rivest. While not recommended for security purposes due to collision vulnerabilities, it remains widely used for file integrity verification in non-security contexts.
SHA-1 (Secure Hash Algorithm 1)
Generates 160-bit (20-byte) hash values. Second-generation hash algorithm designed by the NSA. Not recommended for security-related purposes since collision attacks were proven possible in 2017.
SHA-224 (SHA-2 Family)
Generates 224-bit (28-byte) hash values. Member of the third-generation SHA-2 family, offering higher security than SHA-1. Suitable for scenarios requiring strong security with performance considerations.
SHA-256 (SHA-2 Family)
Generates 256-bit (32-byte) hash values. The most widely used algorithm in the SHA-2 family, extensively used in digital signatures and blockchain. Currently considered the optimal balance between security and performance.
SHA-384 (SHA-2 Family)
Generates 384-bit (48-byte) hash values. High-security version of the SHA-2 family, providing stronger security guarantees than SHA-256. Commonly used in enterprise applications requiring higher security levels.
SHA-512 (SHA-2 Family)
Generates 512-bit (64-byte) hash values. The most secure version in the SHA-2 family, providing the highest level of security. Particularly suitable for critical data protection and high-security requirements.
SHA3-224 (SHA-3 Family)
Generates 224-bit (28-byte) hash values. Member of the fourth-generation SHA-3 family, based on the Keccak algorithm. Provides different security guarantees than SHA-2 as the new generation cryptographic hash standard.
SHA3-256 (SHA-3 Family)
Generates 256-bit (32-byte) hash values. The most commonly used version in the SHA-3 standard, designed to replace SHA-2. Features a novel sponge construction design providing unique security characteristics.
SHA3-384 (SHA-3 Family)
Generates 384-bit (48-byte) hash values. High-strength version of the SHA-3 family, providing enhanced security. Suitable for applications requiring long-term security guarantees.
SHA3-512 (SHA-3 Family)
Generates 512-bit (64-byte) hash values. The most secure version in the SHA-3 family, providing the highest level of quantum computing attack resistance. Suitable for scenarios with extremely high security requirements.
RIPEMD160 (RACE Integrity Primitives Evaluation Message Digest)
Generates 160-bit (20-byte) hash values. Developed by the EU RACE project, independent of the SHA family. Well-known for its use in Bitcoin, primarily used for generating Bitcoin addresses. Provides security guarantees different from the SHA series.
