0 of 0 ratings

Calculate SHA-3/256 hashes. Generate a secure, 64-character hexadecimal cryptographic digest from any text input.

The SHA-3/256 Hashing Algorithm

A sha3-256 generator calculates the SHA-3/256 hash, which is part of the SHA-3 family. It computes a 256-bit message digest represented as a 64-character hexadecimal string. SHA-3 is based on the Keccak sponge construction, offering high cryptographic strength for modern applications.

Modern Data Integrity Checks

Because of its sponge construction, the sha-3/256 hash generator is highly resistant to collision and length extension attacks. It is widely used to verify the integrity of files, software packages, and secure web transmissions.

Password Security Warning

Like other algorithms in the SHA-3 family, SHA-3/256 is a fast hashing function. If a database is compromised, attackers can compute billions of hashes per second using GPUs. Therefore, do not use SHA-3/256 as a standalone algorithm for user password storage; instead, select Bcrypt or other slow, salted hashing standards.

Details - FAQ

SHA-3/256 is a secure 256-bit cryptographic hash function in the SHA-3 family, producing a 64-character hexadecimal signature.

The output is a 64-character hexadecimal string.

Yes, SHA-3/256 is cryptographically secure and resistant to all known collision attacks.

No. It is a fast hashing function. For secure user database password records, use slow algorithms like Bcrypt.
