Signing the Tcl Scripts Example

The following example shows how to sign the Tcl scripts:
Host% openssl smime -sign -in hello -out hello.pk7 -signer cert.pem -inkey privkey.pem
-outform DER -binary
Host% ls -l
total 40
-rw-r--r--
-rw-r--r--
-rw-r--r--
-rw-r--r--
-rw-r--r--

Verifying the Signature Example

The following example shows how to verify the signature:
Host% openssl smime -verify -in hello.pk7 -CAfile cert.pem -inform DER -content hello
puts hello
puts "argc = $argc"
puts "argv = $argv"
puts "argv0 = $argv0"
puts "tcl_interactive = $tcl_interactive"
Verification successful

Converting the Signature with Nonbinary Data Example

The following example shows how to convert the Tcl signature with nonbinary data:
#Cisco Tcl Signature V1.0
Then append the signature file to the end of the file.
Host% xxd -ps hello.pk7 > hello.hex
Host% cat my_append
#!/usr/bin/env expect
set my_first {#Cisco Tcl Signature V1.0}
set newline {}
set my_file [lindex $argv 0]
set my_new_file ${my_file}_sig
set my_new_handle [open $my_new_file w]
set my_handle [open $my_file r]
puts $my_new_handle $newline
puts $my_new_handle $my_first
foreach line [split [read $my_handle] "\n"]
set new_line {#}
append new_line $line
puts $my_new_handle $new_line
