About SHA-1 Checksum
Computes the 40-character hex SHA-1 digest of your input. SHA-1 is cryptographically broken for collision resistance and must not be used for signatures or password storage — but it remains common for git object IDs, legacy checksums, and interoperability with older systems, which is what this tool is for.
