ManSun,
I don't think it's a matter of weak cryptographic algorithm. Software protection against cracking has not much to do with cryptographic algorithms....my sister, without cryptographic knowledge, could wait till the program is decrypted in memory and user LordPE do dump the decrypted program in memory
About the rest of your question...maybe you should give more details about what you want to know exaclty, and not asking that general question that could be answer in Armadillo's help
