Is there any software which can encrypt files utilizing GPU cores? I heard it's possible with the Nvidia's CUDA toolkit. Basically, what options do I have if I need a very fast encryption/decryption of large files (gigabytes) without compression?
You know, GPGPU isn't something which does everything magically quicker. You're most likely better of using AES-NI.

"cat /proc/cpuinfo | grep aes"
If you CPU supports native AES encryption you'll get very high performance letting the CPU do the job.
