-Library which implements basic work with RSA encryption + decryption
-also using authoring hash-cookie
-
-maintainer smal (Serhiy Voyt)
-smalgroup@gmail.com
-
-Before use read carefully readme.txt and define varaibles below
-
-This script is a part of ATutor LDAP-authoring module and it's required to right work all LDAP-authoring in ATutor. RSA
-
-Before use this script you must check your system to folowing:
-1.In your system must be installed OpenSSL package - required to generate private key.
-2.In PHP must be enabled OpenSSL Functions - required to rsa.inc.php (see phpinfo() to check this)
