The use of a marker in a file to assist in the signing and/or verification of the file. The marker is recognized by the signing authority. The marker has a certain execution transparent context that reduces or eliminates the impact of the marker on execution. A signing authority accesses the file, finds the marker within the file, and identifies the execution transparent context system. The signing authority then uses the execution transparent context system to insert a signature with the same execution transparent context. A verification system finds the marker, identifies the execution transparent context of the marker, identify the execution transparent signature, and uses the execution transparent context system to then extract the signature from the execution transparent signature. That signature may then be used to verify that the file has not changed since it was signed. |
