Default -CAfile location: /etc/ssl/certs/ca-certificates.crt

Please send bug-reports to Michal.Trojnara@stunnel.org

osslsigncode is a small tool that implements part of the functionality of the Microsoft
tool signtool.exe - more exactly the Authenticode signing and timestamping.
It can sign and timestamp PE (EXE/SYS/DLL/etc), CAB, CAT, MSI and APPX files,
as well as script files with extensions .ps1, .ps1xml, .psc1, .psd1,
.psm1, .cdxml, .mof and .js,
supports getting the timestamp through a proxy as well.
osslsigncode also supports signature verification, removal and extraction.

--version | -v         = print osslsigncode version and usage
--help                 = print osslsigncode help menu

Commands:
add                    = add an unauthenticated blob or a timestamp to a previously-signed file
attach-signature       = sign file using a given signature
extract-signature      = extract signature from a previously-signed file
extract-data           = extract a data content to be signed
remove-signature       = remove sections of the embedded signature on a file
sign                   = digitally sign a file
verify                 = verifies the digital signature of a file
