MD5 generates a 128-bit hash value and is known for its fast computation speed. It is widely used for file verification, cache identifiers, and similar purposes. However, due to known collision vulnerabilities, it is no longer suitable for password storage or high-security applications.
CRC32 is a cyclic redundancy check algorithm that generates a 32-bit checksum. It is extremely fast and commonly used to detect errors in data transmission or file storage, such as in ZIP and PNG formats. It is not an encryption algorithm and does not provide security protection.
CRC64 is an enhanced version of CRC32 that uses a 64-bit checksum, providing a lower error probability and better reliability. It is suitable for large files, databases, and distributed storage integrity verification. Common variants include CRC-64-ECMA and CRC-64-ISO.
SHA-1 generates a 160-bit hash value and was once widely used for digital signatures and certificate verification. Due to discovered security weaknesses, it is no longer recommended for security-sensitive applications.
SHA-224 is part of the SHA-2 family and provides better security than SHA-1. It produces a 224-bit hash value and is suitable for scenarios requiring strong security with a shorter hash length.
SHA-256 is one of the most widely used secure hashing algorithms today. It generates a 256-bit hash value with high security and is commonly used in HTTPS, blockchain technology, digital signatures, and password verification.
SHA-384 is based on the SHA-512 design and produces a 384-bit hash value. It offers stronger security and is suitable for high-security data verification and encryption systems.
SHA-512 generates a 512-bit hash value and provides the strongest collision resistance among these algorithms. It is suitable for highly secure environments, large-scale systems, and sensitive data protection, although it requires more computational resources.
