====== RTI_Crypto function ======


 
==== Description ====
 
An OpenInsight wrapper for MD3 and SHA1 encryption.  The RTI_Crypto provides for the ability to create encrypted values for authentication purposes.  The function is a one-way hash and cannot be unencrytped via the function.
 
==== Syntax ====
 
ans = RTI_Crypto( method, param1, param2, param3 )
 
==== Parameters ====
 
The function has the following parameters:

^Parameter^Description^
|method|The methods are:\\ \\ HEX_MD5\\ \\ B64_MD5\\ \\ STR_MD5\\ \\ HEX_HMAC_MD5\\ \\ B64_HMAC_MD5\\ \\ STR_HMAC_MD5\\ \\ HEX_SHA1\\ \\ B64_SHA1\\ \\ STR_SHA1\\ \\ ANY_SHA1\\ \\ HEX_HMAC_SHA1\\ \\ B64_HMAC_SHA1\\ \\ ANY_HMAC_SHA1\\ \\ STR_HMAC_SHA1|
|param1|Parameter value is based on the cryptographic method used.|
|param2|Parameter value is based on the cryptographic method used.|
|param3|Parameter value is based on the cryptographic method used.||

 
==== Usage ====
 
retVal = RTI_Crypto( "HEX_MD5", string )

retVal = RTI_Crypto( "B64_MD5", string )

retVal = RTI_Crypto( "STR_MD5", string )

 

retVal = RTI_Crypto( "HEX_HMAC_MD5", key, data )

retVal = RTI_Crypto( "B64_HMAC_MD5", key, data )

retVal = RTI_Crypto( "STR_HMAC_MD5", key, data )

 

retVal = RTI_Crypto( "HEX_SHA1", string )

retVal = RTI_Crypto( "B64_SHA1", string )

retVal = RTI_Crypto( "STR_SHA1", string )

retVal = RTI_Crypto( "ANY_SHA1", string, e )

 

retVal = RTI_Crypto( "HEX_HMAC_SHA1", key, data )

retVal = RTI_Crypto( "B64_HMAC_SHA1", key, data )

retVal = RTI_Crypto( "ANY_HMAC_SHA1", key, data, e )

retVal = RTI_Crypto( "STR_HMAC_SHA1", key, data )

 
==== Returns ====
 
An encrypted value.
 
==== Remarks ====
 
This function implements cryptographic functions from http:%%//%%pajhome.org.uk/crypt/md5/index.html.  Review http:%%//%%pajhome.org.uk/crypt/md5/index.html to see code and examples of usage.  The scripts are implemented verbatim in OpenInsight without change and without need to access external webserver.
