OpenSSL can extract documents from P7M files
I received a signed message in P7M format and wanted to extract the contents - possibly from the command line. I initially thought that GnuPG would get the job one, to no avail.
openssl smime -decrypt -verify -inform DER \ -in $file_input_name -noverify -out $file_output_name
As it happens, we need to put both the initial
-verify and the
-noverify to skip verification and just save the data. I only
tried it on an input file with one single contained file inside, but
still it’s a lot useful!
Stay safe folks!
