What is SHA1?

SHA1 is a cryptographic hash function that produces a 160-bit hash value. Although considered weaker than SHA256, SHA1 is still used for legacy systems and checksum verification.

How to verify a SHA1 checksum

  1. Download the file from the official source.
  2. Find the official SHA1 checksum provided.
  3. Generate the SHA1 using this tool.
  4. Compare both values exactly.
  5. If they match, the file is authentic.

Is SHA1 secure?

For stronger security, use SHA256 instead.

SHA1 is no longer recommended for modern cryptographic security applications. For stronger security, use SHA256 instead.
