I reverse an
.exe file with IDA.
I see a function that appears to be encrypting something by generating some random numbers.
It there any tool to identify if it is a known encryption algorithm?

Signsrch is a somewhat old tool that searches for signatures and magic values for different encryption and hash algorithms. I had a collection of other similar tools in the past, so I believe you can find other related tools by googling for a while.
There's a IDA plugin re-implementation of the same plugin here, you may wanna use it instead.
