About the encrypt / decrypt text
Encrypts and decrypts short pieces of text with a passphrase using AES, TripleDES, Rabbit or RC4. The passphrase is stretched into a key and the result is Base64-encoded, so it survives being pasted into a config file or a message.
Frequently asked questions
Is this strong enough for real secrets?
For notes and scratch data, yes. For production secrets use a key management service or age/GPG — passphrase-derived keys are only as strong as the passphrase, and this format carries no authentication tag.
Why will my ciphertext not decrypt?
Almost always a passphrase typo, a mismatched algorithm, or whitespace picked up when copying. The Base64 blob must be byte-identical, including any trailing equals signs.
