signcode \- Digitally sign an PE executable using an X.509 certificate.
.B signcode [options] filename
Digitally sign an PE executable (CLR assembly, Win32 EXE or DLL) using an
X.509 certificate and it's associated private key. The signature is compatible
with Authenticode(r) and can be validated with chktrust (either on Windows or
on any platform supported by Mono).
.I "-spc spcfile"
The Software Publisher File (spc) that contains the X.509 certificate chain
used to digitally sign the PE executable.
.I "-v pvkfile"
The Private Key File (pvk) that contains the private key used to digitally
sign the PE executable. This private key must match the public key inside the
publisher X.509 certificate.
.I "-a md5 | sha1"
The hash algorithm used in the digital signature of the PE executable. The
default algorithm is MD5.
.I "-$ individual | commercial"
Add information about the publisher, i.e. if the signature is generated by an
individual or a commercial entity.
.I "-n description"
Add a textual description of the signed file.
.I "-i url"
Add a URL associated to the publisher or the signed file.
.I "-t url"
URL to a timestamp service to countersign the PE executable. Countersignature
is required if you want the PE executable signature to be valid after the
publisher certificate expires. The countersignature proves that the publisher
had a valid (non-expired) certificate when the PE executable was signed.
.I "-tr #"
Number of retries to get a timestamp for the countersignature.
.I "-tw #"
Delay (in seconds) between the retries to get a timestamp for the countersignature.
.I "-k name"
CryptoAPI key container name (when not using -v).
.I "-p name"
CryptoAPI provider name (when not using -v).
.I "-y #"
CryptoAPI provider type (when not using -v or -p).
.I "-ky signature | exchange | #"
CryptoAPI key type (when not using -v).
.I "-r localMachine | currentUser"
CryptoAPI key location (when not using -v).
.I "-help", "-h", "-?", "/?"
Display help about this tool.
Assemblies are PE files that can also be strongnamed using the sn.exe tool. The
order of code signature is important if a file requires both an Authenticode
and a strongname signature. Strongname must be applied before the Authenticode
signature. Applying a strongname after the Authenticode signature, like
re-signing an assembly (e.g. delay-sign), will invalidate the Authenticode
signcode cannot generate Authenticode signatures for CAB files.
