Collaboration diagram for Signing related debug messages:

Explanation of the abstract signing related debug messages.

MySigning-related log messages, format: [!]SYSTEM:SUB SYSTEM:MESSAGE

[!] Exclamation mark is prepended in case of error or warning
SYSTEM:
- SGN messages emitted by MySigning
SUB SYSTEMS:
- SGN:INI from signerInit
- SGN:PER from signerInit
- SGN:PRE from signerPresentation
- SGN:SGN from signerSignMsg
- SGN:VER from signerVerifyMsg
- SGN:SKP from signerSignMsg or signerVerifyMsg (skipSign)
- SGN:NCE from signerProcessInternal (signerInternalProcessNonceRequest)
- SGN:BND from the signing backends
