Within this library you get strong encryption functions based on RSA, DES, SHA1 methods right inside the server.This maybe very usefull for protecting security sensitive data. Implementing encryption/decryption on server side, makes you independant from front-end, provide speed and better flexibility of front-end implementation. This library is well known and listed in usenet MSSQL FAQs now it is ported to Oracle ! Limited version can crypt by RSA method up to 21 chars with 256 bit key.
