Base64 è un metodo di crittografia sicuro?

No, Base64 è una codifica, non una cifratura: chiunque può decodificarla senza bisogno di una chiave segreta. Serve per rappresentare dati binari come testo, non per proteggere informazioni sensibili.

Che differenza c'è tra ROT13 e XOR con chiave?

ROT13 è una sostituzione fissa delle lettere, sempre reversibile allo stesso modo. XOR con chiave usa una parola segreta per l'operazione: è leggermente più difficile da invertire senza conoscere la chiave, ma resta comunque debole per usi seri.

No, tutte le codifiche e decodifiche avvengono localmente nel browser tramite JavaScript.

Encode and Decode Text Online — Base64 ROT13 ROT47 Morse XOR

When to use this text encoding tool

Encode and decode text with Base64, ROT13, ROT47, keyed XOR, Morse and reversal — useful for technical exercises, light obfuscation, or compatibility with systems that require these formats.

When to use it

You need to quickly encode or decode a string in Base64, Morse or ROT13 for testing or debugging.
You want to hide text from casual, surface-level reading (not from a real attack).

When NOT to use it

You need real, secure encryption to protect sensitive data: Base64, ROT13 and similar are not encryption methods, just reversible encodings with no robust secret key.

Alternatives

For real encryption with a secret key, use our AES text cipher tool.
Standard cryptographic libraries (Web Crypto API, OpenSSL) for applications that require actual security.

Common mistakes

Using Base64 or ROT13 thinking they protect sensitive data: they are encodings, not encryption, and anyone can reverse them without a key.
Confusing weak-key XOR with secure encryption: without proper key management, XOR is easily reversible.

Frequently asked questions about text encoding

No, Base64 is an encoding, not an encryption: anyone can decode it without needing a secret key. It's used to represent binary data as text, not to protect sensitive information.

ROT13 is a fixed letter substitution, always reversible in the same way. Keyed XOR uses a secret word for the operation: it's slightly harder to reverse without knowing the key, but it's still weak for serious use.

No, all encoding and decoding happens locally in your browser via JavaScript.
