Checksum Aide
Hash code calculation utility.

Checksum Aide (aka, "Checksum-Aide") is a free utility used to generate hash codes (or checksum codes). You can use this tool to verify that a program you downloaded from the internet has not been corrupted or tampered with.

If you are a developer, you can use this tool to generate your own hash codes so that your user can confirm the authenticity of your software.

Checksum-Aide can generate up to 11 different hash codes (including SHA-256). You can use it to get the hash code for a block of text or you can calculate the hash code for a file on your computer. You can also calculate the hash codes for multiple files at one time.

Below, you will find various versions of Checksum-Aide including:
    • Checksum Aide 32 Bit
    • Checksum Aide 64 Bit
    • Checksum Aide 32 Bit Portable
    • Checksum Aide 64 Bit Portable
