Review on BouncyCastle Crypto by Martin Alvarez

I have been using bouncycastle through one of my projects for creating digital signatures, encryption etc without worrying about any security issues. There was no major problem that came across while working with this library. But at times when i needed to write some custom functions it was a bit painful as there were many difficulties involved while writing code. For example when you are doing AES or hash algorithm implementation which requires certain byte/char array data processing then sometimes its difficult to use those algorithms properly in Java language itself instead if we want to do so we need to create intermediate C++ files. By using this library i got rid of all these problems related to security concerns by giving access control to specific users only who require such kind of sensitive information rather than making available it publicly over the internet. Its best software for generating secure messages like e commerce websites where customers can.
