This tool calculates the SHA1 (Secure Hash Algorithm 1) hash of a string. SHA1 produces a 160-bit (20-byte) hash value, known as a message digest, typically rendered as a 40-digit hexadecimal number.
How to use this SHA1 tool
- Enter the text you want to hash.
- The SHA1 hash will generate automatically.
- Toggle “Uppercase Output” for uppercase characters.
- Toggle “Calculate per line” to generate a separate hash for each line of input.
Features
- Instant Calculation: Hashes are generated as you type.
- Batch Processing: Use “Calculate per line” to hash a list of strings.
