File hashes and checksum comparison
File Hash

Choosing a hash or password tool
1Does a matching checksum mean a file is safe?
A match means the file content’s hash equals the expected value you entered. It is not a malware scan or proof of origin. Obtain the expected checksum from a separate trusted source.
2Which hashes are supported?
SHA-256, SHA-384 and SHA-512 are supported. Hashes depend on file contents, not filenames, so renaming alone does not change the hash. This tool does not compare MD5 or SHA-1 checksums.
3Do you keep generated passwords?
No. Passwords use the browser’s secure random generator and can be copied or saved as TXT, but this is not a password vault or recovery service. Manage your clipboard contents and saved files yourself.
