Pistitium.Licenser

Pistitium.Licenser Provides a framework to:

• Provides a framework to generate unique license keys based on:

  • String

  • Hardware Identifier

    • HardwareIdentity class uniquely identifies computer hardware on the running machine

  • Guid

• Allows for generation of:

  • Evaluation License Key (1 Month Expiration)
  • Evaluation License Key with custom expiration
  • Registration License Key (1 Year Expiration)
  • Registration License Key with custom expiration
