Password Exchange

PwExchange is a simple password exchange tool that allows you to share passwords with your friends or colleagues in a secure way. The tool uses a symmetric encryption algorithm to encrypt the password and then sends it to the recipient. The recipient can then decrypt the password using the same tool for one-time use.

Encryption Algorithm

The tool uses argon2 for key derivation and AES for encryption. Each secret is encrypted with a unique key. We use a server side key, a random client secret, and a random salt to derive the key. The key is then used to encrypt the secret.

Only with this three keys, the secret can be decrypted.
