Frequently Asked Questions
SHA256 (Secure Hash Algorithm 256-bit) is a cryptographic hash function that generates a fixed-size 256-bit (32-byte) hash value from any input. It's part of the SHA-2 family and is widely used for digital signatures, file integrity verification, and secure password hashing.
Yes, SHA256 is considered cryptographically secure and is widely used in modern security applications. Unlike its predecessors (MD5 and SHA1), SHA256 has not been compromised and is recommended for security-critical applications.
Our SHA256 Generator processes your input text entirely in your browser using JavaScript. The text is converted into a fixed-length string of 64 hexadecimal characters. No data is sent to our servers, ensuring complete privacy and security.
SHA256 is used in many security applications and protocols, including:
• Digital signatures and certificates
• Blockchain and cryptocurrency (like Bitcoin)
• File integrity verification
• Password hashing (with additional salt)
• SSL/TLS security protocols
While SHA256 is cryptographically secure, for password hashing specifically, it's recommended to use specialized password hashing functions like bcrypt, Argon2, or PBKDF2. These algorithms are designed with additional features like salt and work factors to better protect against password cracking attempts.
