In embodiments of the present invention, public private key pair is created, such as strong name instrument (Sn.exe) can be used to create one
Key pair.Key file generally all has .snk file extension.A key is created under CMD, key
Enter to issue orders：Sn-k<file name>In this order,<file name>It is an output file for including key pair
Name.If example below is one key-pair file sn-k sgKey.snk for being named as sgKey.snk of establishment, you wish to postpone
Identify procedure set and also be intended to control whole key pair, you can be issued orders with one and generate a pair of secret keys pair, then close from this
Key centering extracts public key to a single file.First, key pair is created：Then, from above sn-k keypair.snk look unfamiliar
Into key-pair file (keypair.snk) in extraction public key, and copy in an independent file：sn-p
Once you create key pair to keypair.snk public.snk, this file must just be placed on strong name marking instrument by you
Its position can be found.When a procedure set is identified with strong name, procedure set connector (Assembly
Linker (Al.exe)) key file relevant with current directory can be found, and it is output to current directory.Using order line work
When tool compiling, this key can also be easily copied under the current directory comprising code module.
