Generate secure SHA-256 hashes from plain-text input. This tool is useful for data integrity verification, password storage, and cryptographic operations.
Supported Tools:
Free online tool to generate and verify SHA256 hashes from text or files directly in your browser. No installation required.
SHA256 (Secure Hash Algorithm 256) is a cryptographic hash function from the SHA-2 family, producing a 256-bit (32-byte) hash, represented as a 64-character hexadecimal string. SHA256 is widely used for password hashing, digital signatures, and file integrity due to its strong security and collision resistance.

Can I generate SHA256 hashes for free?
Yes. This tool lets you create SHA256 hashes from text or files instantly in your browser.
What is the length of a SHA256 hash?
SHA256 produces a 256-bit (32-byte) hash, represented as a 64-character hexadecimal string.
Can I hash a file?
Yes. Upload a file, and the tool will compute its SHA256 hash.
Can SHA256 be reversed?
No. SHA256 is a one-way hash. Only known hash databases or brute-force methods may match hashes to original input.
What is SHA256 used for?
SHA256 is used for password hashing, digital signatures, file integrity, and blockchain applications due to its strong security.
What is SHA256 algorithm?
SHA256 is part of the SHA-2 family, designed to improve security over SHA1 and MD5. It ensures data integrity and cryptographic security.
