128/256 bit Encryption Level
The encryption level refers to the number of bits used to generate encryption key. PositiveSSL supports up to 256-bit encryption. That is, if your web server and your site visitor’s browser
support 256-bit encryption, then the encryption key for the SSL session would be 256. If 256-bit encryption is not supported either by your server or your site visitor’s browser, the SSL session would be 128-bit.
