Supports variant key management only - no other key management modes yet.
Is a Java process that simulates a financial services Hardware Security Module (HSM). A class called ServerProcess starts a plain-text TCP service to simulate an HSM Request/Response transaction. config.properties contains runtime settings and master keys
Sample usage:
build: $ mvn clean package Start the HSM Simulator as follows: from a command prompt: $ Java -cp ./target/hsmsimulator-0.0.1-SNAPSHOT-standalone.jar com.goyoung.crypto.hsmsim.ServerProcess
1. User telnets to IP specified in the properties file $ telnet localhost 8080 2. User sends a command 10: <10#4##D#> // request to generate double length key for 2TDEA TripleDES 3. User receives command 10 response (20): <20#F6DFEAAD648A7A17E5A9CE0796440D9D##63E0#> // response of double length key for 2TDEA 3DES //key is not encrypted by any master key, //response contains a 4 char Key Check Value, KCV at the end 4. User Sends command 10 : <10#1#9007B8751BB7AB4EE355AF51A716113F#D#> // generate double length key for 2TDEA 3DES, encrypt under variant 1 of the MFK and variant 1 or KEK, //Provided KEK previously encrypted under variant 0 of MFK 5. User receives command 10 response (20): <20#6CEDF649AAA492B90F909AD3A6D2D54F#64B343D9C5AB8C8692122EFDA11D62F6#07CB#> // double length key for 2TDEA 3DES encrypted by MFK.variant.1 (leftmost and KEK.variant.1 with char Key Check Value (rightmost), and KCV at the right end Example: 
Let's generate a key:
$ telnet localhost 8080 Trying ::1... Connected to localhost. Escape character is '^]'. <10#4##D#> <20#D3E07B0C441E1F9E52CB063D3592F05B##DD1B#>Included libraries: see the project file for libraries required to build the project:
