About these tools

AppErgo security tools cover practical needs: creating a strong password, producing a modern SHA hash, or calculating classic fingerprints such as MD5, SHA-1 and CRC32 for compatibility checks.

The password generator helps create a combination based on your criteria. The SHA generator focuses on SHA-256, SHA-384 and SHA-512 for modern use. The MD5, SHA-1 and CRC32 tool is mainly useful for recognizing or checking legacy formats, without presenting them as recommended choices for current security.
