About this Tool
The SHA-256 algorithm generates an almost-unique, fixed-size 256-bit (32-byte) hash. It is the industry standard for cryptographic security, widely used for data integrity verification, password hashing architectures, and blockchain technology. Enter any text string to instantly compute its SHA-256 hexadecimal hash.
Frequently Asked Questions
Um hash SHA-256 pode ser descriptografado de volta para texto?
Não. SHA-256 é uma função de hash criptográfico de via única, não um algoritmo de criptografia. É matematicamente inviável reverter o hash de volta ao plain text original.
Will the same text always generate the same hash?
Yes. SHA-256 is deterministic. Identical inputs will always produce the exact same hash output, which is why it is perfect for verifying file integrity or comparing passwords.
