VIPole is a secure instant messenger powered by strong encryption technologies (AES-256, RSA-3072) that perfectly guard sensitive communications and files from prying eyes and surveillance efforts. VIPole strongly encrypts instant messages, group chats, voice calls, video calls and files so that no third-party is able to listen to conversations or tap into a message or file. Software architecture prevents even the employees of the VIPole service provider from intercepting or disclosing a user's data as all the encryption occurs locally on user device and arrives on the server already encrypted.
