The use of keys provides additional security. This security is also ensured in the long term by the following possibilities:
The public key files for the existing key pair sets can be created again. This is necessary, for example, if a public key file had been accidentally deleted or manipulated in any other way.
A key pair set can be replaced by a completely new key pair set. The most recent public key is identified by the key reference with the highest value in the file name. openFT supports a maximum of three key pair sets at the same time. However, multiple keys should only exist until the most recent public key has been made available to all partner systems.
Key pair sets that are no longer needed can (and should!) be deleted immediately.
