FAQ

Which algorithms are supported?

AES, DES/3DES, RC4, RSA. AES is recommended for most scenarios.

Is my file uploaded?

No. All encryption runs locally in your browser. Only anonymous usage stats are recorded.

Why is RSA slow or failing?

RSA is for small data. For file encryption, use symmetric algorithms such as AES.
