Security

Your privacy is our priority.

Privacy is matter, no matter person or industry, that's our primary goal and our core value.

Secure communication deserves attention

Even though privacy and security are invisible, we still strictly control them for users.

Letstalk employs multiple layers of encryption to protect your data and messages, no matter at rest or in transit:

  • Your profiles are cryptographically hashed with multiple rounds of salted SHA256.
  • All messages are encrypted with AES256. Each message has a different encryption key.
  • All encryption keys of messages are time-limited and restricted by the number of times.
  • Message encryption keys are encrypted with RSA.
