The decryption algorithm is very simple and is the same for all ISTA dlls. However each method the strings are referenced from has it's own set of seed constants, so even if I would give the algorithm on the silver plate, I can't give you the universal way to find said constants.

Just decompile, look at the code, find the constants, then run decryption algorithm using said constants and encrypted string. The result will be decrypted string smile

P.S. Of course universal decryptor could most likely be developed, but the issue of finding said constants does not make it worth the time required to make it.

they are obfuscated using dotfuscator tool - not a very sophicated obfuscator.

use de4dot - works a charm - decrypts the strings and in most cases unwraps the control obfuscation that dotfuscator adds.

enjoy
thanks and rep if you find this useful.
