GEMDS Firmware Packaging Signing Utility (pkgsigner) 06-6671A01 Rev. 0.3.0
Built: Jan 7 2013 11:25:34
Usage:
To verify and sign a package:
pkgsigner -v verifycert -k privkey -P password -p pubcert -f infile -o outfile
where: verifycert = The filepath a public certificate to be used to verify the
signature of the infile if and the infile has been
previously signed.
privkey = The filepath for the private key to be used to create
a signed package.
password = The optional password, if the private key is encrypted
pubcert = The filepath for the public certificate corresponding to
the privkey. This is used to store a hash of the certificate
information, to aide lookup of the appropriate public key
during signature verification
infile = The filepath for package file (input)
outfile = The filepath for signed package file (output)
To display package info and verification status:
pkgsigner -l -v verifycert -f infile
where: verifycert = The filepath a public certificate to be used to verify the
signature of the infile if and the infile has been
previously signed.
infile = The filepath for package file (input)
Users can verify that a firmware package file came from GE MDS by using the CST. The following
example shows how to verify a signed firmware package file came from GE MDS by using the firmware
file ge_signed_package.mpk and by using the GE MDS provided public certificate ge_pubcert.pem.
./pkgsigner -l -v ge_pubcert.pem -f ge_signed_package.mpk
Processing file: 'ge_signed_package.mpk'
