Having used cryptographic techniques on a number of programs with PHP, and knowing very well its basic concepts as well as its different implementations, we can surely provide you with the result you are looking for. Standard PHP functions, with the support of operating system modules, can reach a very good level of security nowadays, but this level can even be increased by adapting them to specific environments. Let us know your specific needs and we will gladly show you how we can help you on this matter. Regards The Bramfeld Team
