decryption
with aes — passphrase-based, runs in your browser with CryptoJS.
This algorithm’s default string output is the salted format familiar from OpenSSL / CryptoJS block ciphers.
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
Online Decryption AES.
Decrypt short strings or files with Aes when you are debugging integrations—not for storing production secrets in plain text.
Algorithm match
Parameters align with common Aes examples from docs and Stack Overflow answers.
Paste-friendly
Move ciphertext between tickets, logs, and this page without line-break damage.
Educational use
Verify what your backend already produced before you blame the client SDK.
Stay off prod keys
Rotate real secrets in your vault; this page is for tests and coursework.
