Hash Generator

How to Use

1. Type or paste text into the input area.
2. Select an algorithm (SHA-1, SHA-256, SHA-384, or SHA-512).
3. The hash value is generated in real time as you type.
4. Click the copy button to copy the hash to your clipboard.

Hash Algorithms

SHA (Secure Hash Algorithm) is a family of cryptographic hash functions. Each algorithm produces a fixed-length output regardless of input size.

• SHA-1 (40 characters): Legacy algorithm. Still used for checksums and Git commit hashes, but not recommended for security purposes due to known collision vulnerabilities.
• SHA-256 (64 characters): The most widely used. Standard for digital signatures (TLS/SSL), blockchain (Bitcoin), data integrity verification, and password hashing.
• SHA-384 (96 characters): A truncated version of SHA-512. Used in government and military applications (NSA Suite B).
• SHA-512 (128 characters): Highest security. Suitable for scenarios requiring maximum collision resistance, such as high-security certificates and large-scale data verification.

Which Algorithm Should I Use?

• General purpose / data integrity: SHA-256
• File checksums / quick verification: SHA-256
• Maximum security requirements: SHA-512
• Legacy system compatibility: SHA-1 (avoid for new security applications)
