How Strong Is It?
X-IM's Encryption Protocols and Algorithms are selected and designed to protect the privacy of your communications well into the foreseeable future and beyond. In other words it is designed well in excess of what is necessary to protect against today's technology. If a million of today's 3 GHz PCs were connected in parallel to break an X-IM key at its weakest point using today's mathematical knowledge, they would take around one trillion years to complete their task* -- hundreds of times longer than it will take for the Sun to expand into a red giant and make the point moot.
Key Sizes
We use highly optimized code to allow the use of large key sizes while keeping all cryptographic operations virtually instantaneous. Encryption technology referred to as "Military Strength" or "Industrial Strength" typically uses 128-bit session keys, 128-bit hash functions, and 1024-bit public/private key pairs. X-IM uses 256-bit session keys, 160-bit hash functions, and 2048-bit public/private key pairs.
