Details on Database Authentication Encryption

Products

• CA Test Data Manager (Data Finder / Grid Tools)

Issue/Introduction

Could you please share additional details on the following items?

1. In GT DataMaker and CA TDM Portal,  please explain how the connections will be encrypted for each database-type(Oracle, DB2 etc.) connection in the connection profiles?
2. Please explain how, where, and what kind of encryption method is used on GT DataMakar and CA TDM Portal for storing the connection credentials?

 

Environment

Test Data Manager
TDM Porta

 

Resolution

Engineering reviewed the gtrep repository database for TDM.
The passwords are stored in the repository using AES-128 encryption. Below is a spreadsheet showing the details of the encryption mechanism used.

ENCRYPTION ALGORITHMS

Algorithm	Type	Proprietary?	Key Strength (bits)	Specific Implementations		Link to Public Domain Code	Products Using	Purpose	Modifications
				Language	Details
AES-128	Symmetric	N	128 (code supports 192-bit and 256-bit keys but is a build configuration)	C++	Rijndael, Chained-Block-Cipher (CBC) mode with randomized Initialization Vector (IV) (16-byte blocks)	http://www.wizardwrx.com/FREEBIES/P6CryptAES.html	Datamaker	Authentication (Password storage)	Inserted into own DLL - aes_dll.dll Small modifications to handle multi-byte data from PowerBuilder code (char to wchar conversions added)
							AgileDesigner	Authentication (Password transmission from Datamaker and to Service Layer (symmetric))
							Test Matching	Authentication (Transmission of credentials to Remote Engine (data source string is symmetrically encrypted))
							Service Layer	Authentication (Password storage and transmission)
							Remote Engine	Authentication (Password transmission)
							Javelin	Authentication (Password storage in XAML)
			128	C#	CBC, PCKS7 Padding, salt according to RFC2898		Javelin	Authentication (Password transmission from Subset)
			128	Java	CBC, PCKS7 Padding, salt according to RFC2898		Subset	Authentication (Password transmission to Javelin)
			128	Java	Rijndael, Chained-Block-Cipher (CBC) mode with randomized Initialization Vector (IV)		None.		Straight conversion from C++ codebase.
			128	Java	Uses sdtandard javax.crypto packages, using algorithm "AES"		FastDataMasker	Masking of data, and masking of cross-reference table (as an option)
AES-256	Symmetric	N	256	C++	Comes as part of 7Zip.		AgileDesigner	IP protection (keep file contents and structures secret)
ElGamal	Asymmetric	N	384 (code supports 8- and 1088-bit keys but only through code changes)	C#	Standard ElGamal, using a Diffie-Hellman key exchange process. Random number generation is done using System.Random class.		Service Layer (beta)	Providing secure authentication between client and service layer.	Needs adaptation to use a provable prime generator (currently uses pseudoprime generator, causing a 5% residual fault rate)
DES	Symmetric	N	56	Java	Uses standard javax.crypto packages, using algorithm "PBEWithMD5AndDES"		Subset	Authentication (Password storage)
							FastDataMasker	Masking of data; - user can specify the encryption algorithm to use, as well as the key, by selecting an option when specifying the masking function.r. No key management is done, and secure memory management delegated to Java libraries.

HASHING ALGORITHMS

Algorithm	Proprietary?	Specific Implementations		Link to Public Domain Code	Products Using	Purpose	Modifications

SHA-1	N	C++	Standard SHA-1	http://www.packetizer.com/security/sha1/	AgileDesigner	Licensing (legacy option from Datamaker)	Inserted into module aes_dll.dll
					DataViz	Licensing (from Datamaker)
					DataMaker	Licensing (uses Datamaker licence by proxy and passes to other products)
					GTDiagrammer	Licensing (from Datamaker)
		Java	java.security implementation		FastDataMasker	Masking data - user can specify the hashing algorithm to use by selecting an option when specifying the masking function.
SHA-256	N	Java	java.security implementation		FastDataMasker	Masking data - user can specify the hashing algorithm to use by selecting an option when specifying the masking function.
SHA-384	N	Java	java.security implementation		FastDataMasker	Masking data - user can specify the hashing algorithm to use by selecting an option when specifying the masking function.
SHA-512	N	Java	java.security implementation		FastDataMasker	Masking data - user can specify the hashing algorithm to use by selecting an option when specifying the masking function.
MD2	N	Java	java.security implementation		FastDataMasker	Masking data - user can specify the hashing algorithm to use by selecting an option when specifying the masking function.
