What is a hash function?
A cryptographic hash function is a mathematical algorithm that maps data of arbitrary size to a fixed-size bit sequence. It is widely used to verify data integrity and in cryptography.
Available Algorithms
- SHA-256: Generates 256-bit hash (64 hex characters). Part of the SHA-2 family, widely used in blockchain and digital certificates.
- SHA-512: Generates 512-bit hash (128 hex characters). Offers greater security than SHA-256, ideal for critical applications.
- SHA-1: Generates 160-bit hash (40 hex characters). Considered obsolete for security, but still used for integrity verification.
Frequently Asked Questions
For security, use SHA-256 or SHA-512. MD5 and SHA-1 are considered insecure for cryptography but still useful for integrity verification.
