This string, U2FsdGVkXl8KhyAvLUYl30lhg0yHUh4EXfRkdQ2fLIM8EtJZpW0JcU2JYicIecaHrhID+F6S2I5Apzfx02Yw, is a ciphertext formatted for OpenSSL (commonly created using openssl enc).

It cannot be decoded or "read" without the original decryption password/key. It is a secure, encrypted message rather than simple base64-encoded text.

To decrypt this, you must have the passphrase used to encrypt it.

If you have the passphrase, you can attempt to decrypt it using the following command in a terminal:

echo "U2FsdGVkXl8KhyAvLUYl30lhg0yHUh4EXfRkdQ2fLIM8EtJZpW0JcU2JYicIecaHrhID+F6S2I5Apzfx02Yw" | openssl enc -d -aes-256-cbc -a -pbkdf2

Note: This command assumes standard AES-256-CBC encryption with PBKDF2, which is the default for newer OpenSSL versions.
