valise · decrypt

ciphertext empty

file none selected

key password

Selecting a file decrypts it to a download; the ciphertext input returns when the file is removed. In key mode the key field below supplies the key. Files up to 1 GiB.

password empty

The key is derived in this tab with Argon2id from the password and the salt stored in the file.

key empty

The key never leaves this tab. Spellcheck is off deliberately: browser spell services can ship what you type to a vendor.

plaintext waiting for input

decrypted file waiting for input

The download link exists only after the whole file authenticated. A wrong key, wrong password or tampered file never produces one.
