This site offers four tasks: text encryption, text decryption, file recovery packages and random AES keys. GCM is the password default; CBC and CTR exist only as raw compatibility options. AES-192 operations use a named local compatibility backend rather than a silent key-size change.
Public content is rendered outside the sensitive workspace. Inputs stay in a separate-origin tool with no advertising, analytics or session replay. That boundary reduces direct form access but does not make a compromised outer page safe. No independent security audit or certification is claimed. See Privacy for hosting and operator details still required before launch.
