About SHA1

SHA1 (Secure Hash Algorithm 1) is a cryptographic hash function that produces a 160-bit hash value, typically expressed as a 40-character hexadecimal number.

SHA1 Characteristics

  • Output Size: 160 bits (20 bytes)
  • Hex Representation: 40 hexadecimal characters
  • Collision Resistance: Broken (collisions found in 2017)
  • Preimage Resistance: Still considered secure
  • Common Uses: Git commit hashes, file integrity (deprecated for security)

Security Note

⚠️ SHA1 is cryptographically weakened and should not be used for security purposes. While it still provides preimage resistance, collision attacks are practical. For secure applications, use SHA-256 or stronger algorithms.

Examples

Input SHA1 Hash
hello aaf4c61ddcc5e8a2dabede0f3b482cd9aea9434d
password 5baa61e4c9b93f3f0682250b6cf8331b7ee68fd8
The quick brown fox jumps over the lazy dog 2fd4e1c67a2d28fced849ee1bb76e7391b93eb12

How to Use

  1. Enter the text you want to hash in the input field
  2. Click "Generate SHA1 Hash"
  3. Copy the resulting hash value
  4. The hash is always 40 characters long (160 bits)
