NAME

       sn - Digitally sign/verify/compare strongnames on CLR assemblies.

SYNOPSIS

       sn [-q | -quiet] [options] [parameters]

DESCRIPTION

       Digitally sign, verify or compare CLR assemblies using strongnames.

       You can use the sn command to create "snk files" using the -k option described below.

CONFIGURATION OPTIONS

       Configuration options are stored in the machine.config configuration file under /configuration/strongNames.

       -c provider
	      Change the default CSP (Crypto Service Provider). Currently not supported in Mono.

       -m [y|n]
	      Use a machine [y] key container or a user [n] key container. Currently not supported in Mono.

       -Vl    List the verification options. The list is kept under /configuration/ strongNames/verificationSettings in machine.config.

       -Vr assembly [userlist]
	      Exempt  the  specified  assembly	from  verification  for  the  specified  user  list.  Currently not supported by sn. You must edit
	      machine.config manually if you require this.

       -Vu assembly
	      Remove the exemption entry for the specified assembly. Currently not supported by sn, you must edit machine.config manually  if  you
	      require this.

       -Vx    Remove all exemptions entries. Currently not supported by sn, you must edit machine.config manually if you require this.

CSP RELATED OPTIONS

       -d container
	      Delete the keypair present in the specified key container.

       -i keypair.snk container
	      Import the specified strongname file into the specified container.

       -pc container publickey
	      Export the public key from the specified CSP container to the specified file.

CONVERSION OPTIONS

       -e assembly output.pub
	      Export the assembly public key to the specified output file.

       -p keypair.snk output.pub
	      Export  the  public  key from the specified strongname key file (SNK) or from a PKCS#12/PFX password protected file to the specified
	      output file.

       -o input output.txt
	      Convert the input file to a CSV file (using decimal).

       -oh input output.txt
	      Convert the input file to a CSV file (using hexadecimal).

STRONGNAME SIGNING OPTIONS

       -D assembly1 assembly2
	      Compare if assembly1 and assembly are the same exception for their signature.  This is done by comparing the hash of the metadata of
	      both assembly.

       -k [size] keypair.snk
	      Create  a new strongname keypair in the specified file. The default key length is 1024 bits and MUST ALWAYS be used when signing 1.x
	      assemblies.  Any value from 384 to 16384 bits (in increments of 8 bits) is a valid key length to sign 2.x assemblies. To ensure max-
	      imum  compatibility  you	may want to continue using 1024 bits keys. Note that there's no good reason, even if it's possible, to use
	      length lesser than 1024 bits.

       -R assembly keypair.snk
	      Re-sign the specified assembly using the specified strongname keypair file (SNK) or a PKCS#12/PFX password protected file.  You  can
	      only  sign  an  assembly	with  the private key that match the public key inside the assembly (unless it's public key token has been
	      remapped in machine.config).

       -Rc assembly container
	      Re-sign the specified assembly using the specified strongname container.

       -t file
	      Show the public key token from the specified file.

       -tp file
	      Show the public key and the public key token from the specified file.

       -T assembly
	      Show the public key token from the specified assembly.

       -Tp assembly
	      Show the public key and the public key token from the specified assembly.

       -v assembly
	      Verify the specified assembly signature.

       -vf assembly
	      Verify the specified assembly signature (even if disabled).

CONFIGURATION FILE

       Strongnames configuration is kept in "machine.config" file. Currently two
	      features can be configured.

       /configuration/strongNames/pubTokenMapping
	      This mechanism lets Mono remap a public key token, like the ECMA token, to another public key for verification. This  is	useful	in
	      two scenarios. First, assemblies signed with the "ECMA key" need to be verified by the "runtime" key (as the ECMA key isn't a public
	      key). Second, many assemblies are signed with private keys that Mono can't use (e.g. System.Security.dll assembly).  A new key  can-
	      not  be  used  because it should change thr strongname (a new key pair would have a new public key which would produce a new token).
	      Public key token remapping is the solution for both problems. Each token must be configured in a "map" entry similar  to	this  one:
	      <map Token="b77a5c561934e089" PublicKey="00..." />

       /configuration/strongNames/verificationSettings
	      It  is often useful during development to use delay signed assemblies.  Normally* the runtime wouldn't allow delay-signed assemblies
	      to be loaded.  This feature allows some delay-signed assemblies (based on their public key token, optionally assembly name and  user
	      name)  to be used like they were fully signed assemblies. [*] Note that Mono 1.0 "runtime" doesn't validate strongname signatures so
	      this option shouldn't be required in most scenarios.
