Countersign Method
Countersigns the existing signature.
procedure Countersign(Level: Integer; SerialSignature: Boolean);
Remarks
Use this method to countersign a signature. Use the Level parameter to provide the desired CAdES level (see below).
SerialSignature specifies whether the new countersignature should be added on the same level of hierarchy as the original signature (signature-over-data, True), or as a true countersignature (signature-over-signature, False).
CAdES defines a number of different 'levels' of signatures. Supported signature levels:
cslUnknown | 0 | Unknown signature level |
cslBES | 1 | BES (Basic Electronic Signature) |
cslEPES | 2 | EPES (Electronic Signature with an Explicit Policy) |
cslT | 3 | T (Timestamped) |
cslC | 4 | C (T with revocation references) |
cslXType1 | 5 | X Type 1 (C with an ES-C timestamp) |
cslXType2 | 6 | X Type 2 (C with a CertsAndCRLs timestamp) |
cslXLType1 | 7 | XL Type 1 (C with revocation values and an ES-C timestamp) |
cslXLType2 | 8 | XL Type 2 (C with revocation values and a CertsAndCRLs timestamp) |
cslBaselineB | 9 | Baseline B (B-B, basic) |
cslBaselineT | 10 | Baseline T (B-T, timestamped) |
cslBaselineLT | 11 | Baseline LT (B-LT, long-term) |
cslBaselineLTA | 12 | Baseline LTA (B-LTA, long-term with archived timestamp) |
cslExtendedBES | 13 | Extended BES |
cslExtendedEPES | 14 | Extended EPES |
cslExtendedT | 15 | Extended T |
cslExtendedC | 16 | Extended C |
cslExtendedXType1 | 17 | Extended X Type 1 |
cslExtendedXType2 | 18 | Extended X Type 2 |
cslExtendedXLType1 | 19 | Extended XL Type 1 |
cslExtendedXLType2 | 20 | Extended XL Type 2 |
cslExtendedA | 21 | Extended A |
cslA | 22 | A (archived) |
