Understanding Hash Algorithms

SHA-2 Family (SHA-256, SHA-512)

A widely used and trusted family of cryptographic hashes. Ideal for general-purpose use like verifying file integrity or creating digital signatures.

SHA-3 Family (SHA3-256, SHA3-512)

The latest standard from NIST. It uses a different internal construction (a “sponge” function) than SHA-2, making it an excellent modern alternative.

BLAKE2 Family (BLAKE2b, BLAKE2s)

Designed to be highly secure and extremely fast, often outperforming the SHA family on modern processors. It’s an excellent choice for applications requiring high performance.

Note on Password Hashing

Functions like Argon2, scrypt, and bcrypt are specifically designed to be slow and computationally expensive. They are meant for server-side use to protect against offline brute-force attacks on stolen password databases. The algorithms in this tool are general-purpose cryptographic hashes and are not suitable for storing user passwords directly.
