decryption
with rc4 — passphrase-based, runs in your browser with CryptoJS.
Ciphertext is CryptoJS’s usual string encoding for this cipher (stream ciphers, not OpenSSL enc-style salt).
Uses the same passphrase as above. The file is read as UTF-8 text and should contain your ciphertext (e.g. the Base64/OpenSSL-style string from this tool).
.txt or plain text
