CONFIG (STRUCT)¶

TYPE CONFIG : STRUCT

Contains the properties of a security policy

These are usable for calculationg the size of the key’s

TYPE PubSubMessageSecurity :
STRUCT
    SignatureKey : ARRAY[0..(udiSignatureKeySize-1)] OF BYTE;
    EncryptionKey : ARRAY[0..(udiEncryptionKeySize-1)] OF BYTE;
    KeyNonce : ARRAY[0..(udiNonceSize-1)] OF BYTE;
END_STRUCT
END_TYPE
