.
A security key, also known as a
cryptographic key
, is a string of randomly or mathematically generated characters that are tied to a specific cryptographic algorithm. These keys are used to:
  • Encrypt plain text to allow users to send text across the internet with confidence that the content is secure.
  • Decrypt the encrypted message so that the text can be read by the intended recipient.
  • Validate that the encrypted message has not been tampered with while in transit.
These are the available
Cybersource
 security keys:
  • Message-Level Encryption (MLE) Keys
  • Meta Keys
  • PGP Keys
  • REST API Keys
  • Secure Acceptance Keys
  • Simple Order Keys
  • SOAP Toolkit Keys
