This file defines each encryption method currently supported by PDX.  
 
 
Methods must use the following parameters: 
     STRING - String to encrypt/decrypt 
     KEY1 - Name of primary encryption/decryption key 
     KEY2 - Name of secondary encryption/decryption key (if required) 
 
Methods must return the following: 
     string - Encrypted or decrypted form of STRING 
     NULL - Error 
 
Sample methods: 
     $$ECR^VAQZZZ(STRING,KEY1,KEY2) - Encrypts STRING using the 
                                      encryption keys KEY1 & KEY2 
     $$DCR^VAQZZZ(STRING,KEY1,KEY2) - Decrypts STRING using the 
                                      decryption keys KEY1 & KEY2 
 
Sample use: 
     S IFN=internal file number for encryption method 
     S STRING="TEST" 
     S KEY1="ABCD1234" 
     S KEY2="ZYXW0987" 
     X ("S X="_^VAT(394.72,IFN,"ECR")) 
     The variable X is now set to the encrypted format of STRING
