For generating these seeds and private key, lmnewgen functionality executes following process:

• Takes the reference of customer provided LM_SEED(X) keys mentioned under machind/lm_code.h.
• Generates unique byte stream based on LM_SEED(X). Third party Certicom provided functionality is used for providing the randomness.
• Certicom internally uses FIPS-186 RNG with the user supplied seeds to generate the byte stream.
• Retrieved byte stream is further used with lmnewgen logic to generates the ENCRYPTION_SEED(X) in lm_seeds.h
• lmnewgen uses certicom provided functionality to generate the private key. This functionality internally uses :
  • unique byte stream
  • Uses FIPS-186 RNG for the uniqueness
