CryptoPad is a service that allows you to store encrypted information without transmitting data in clear form to a remote server . The algorithm is implemented by pre-encrypting data on the client side before sending, while the password, data and keys are not sent to the server in clear text.
The main difference of the CryptoPad service is that the information is only encrypted on the server, and even the server owner cannot read the information, since encryption is done on the client side.
For encryption, the AES algorithm with a key length of 256 bits is used. JavaScript is used for client side encryption.
The service allows you to store up to 64 kilobytes of information.
