PPTP VPN uses Microsoft Point-to-Point Encryption (MPPE). MPPE is a protocol for encrypting data across Point-to-Point Protocol (PPP) and Virtual Private Network (VPN) links. It uses the RSA RC4 encryption algorithm. MPPE supports 40-bit and 128-bit session keys, which are changed frequently to improve security..
