Sep 04, 2018 Support for decoding RSA Private Key, Private Key and Public Key. Example Generate public certificate + privatekey. Generate public certificate + privatekey using: openssl req -x509 -sha256 -nodes -days 365 -newkey rsa:2048 -keyout private.key -out certificatepub.crt Code example 1 - decode private key into RSAParameters.

-->

The RS256 token requires private and public key pair. One can generate them with openssl.Currently the library accepts binary representation of the keys. To create a private key run: openssl req -x509 -sha256 -nodes -days 365 -newkey rsa:2048 -keyout./privateKey.key -out./certificate.crt grep -v ^- privateKey.key base64 -d priv.dat.
Press generate and follow instructions to generate (public/private) key pair. Create a new 'authorizedkeys' file (with Notepad): Copy your public key data from the 'Public key for pasting into OpenSSH authorizedkeys file' section of the PuTTY Key Generator, and paste the key data to the 'authorizedkeys' file.

The Strong Name tool (Sn.exe) helps sign assemblies with strong names. Sn.exe provides options for key management, signature generation, and signature verification.

Warning

Do not rely on strong names for security. They provide a unique identity only.

For more information on strong naming and strong-named assemblies, see Strong-Named Assemblies and How to: Sign an Assembly with a Strong Name.

The Strong Name tool is automatically installed with Visual Studio. To start the tool, use the Developer Command Prompt (or the Visual Studio Command Prompt in Windows 7). For more information, see Command Prompts.

Note

On 64-bit computers, run the 32-bit version of Sn.exe by using the Developer Command Prompt for Visual Studio and the 64-bit version by using the Visual Studio x64 Win64 Command Prompt.

At the command prompt, type the following:

Syntax

Parameters

Option	Description
`-a identityKeyPairFile signaturePublicKeyFile`	Generates AssemblySignatureKeyAttribute data to migrate the identity key to the signature key from a file.
`-ac identityPublicKeyFile identityKeyPairContainer signaturePublicKeyFile`	Generates AssemblySignatureKeyAttribute data to migrate the identity key to the signature key from a key container.
`-c [csp]`	Sets the default cryptographic service provider (CSP) to use for strong name signing. This setting applies to the entire computer. If you do not specify a CSP name, Sn.exe clears the current setting.
`-d container`	Deletes the specified key container from the strong name CSP.
`-D assembly1 assembly2`	Verifies that two assemblies differ only by signature. This is often used as a check after an assembly has been re-signed with a different key pair.
`-e assembly outfile`	Extracts the public key from assembly and stores it in outfile.
`-h`	Displays command syntax and options for the tool.
`-i infile container`	Installs the key pair from infile in the specified key container. The key container resides in the strong name CSP.
`-k [keysize] outfile`	Generates a new RSACryptoServiceProvider key of the specified size and writes it to the specified file. Both a public and private key are written to the file. If you do not specify a key size, a 1,024-bit key is generated by default if you have the Microsoft enhanced cryptographic provider installed; otherwise, a 512-bit key is generated. The keysize parameter supports key lengths from 384 bits to 16,384 bits in increments of 8 bits if you have the Microsoft enhanced cryptographic provider installed. It supports key lengths from 384 bits to 512 bits in increments of 8 bits if you have the Microsoft base cryptographic provider installed.
`-m [y\|n]`	Specifies whether key containers are computer-specific, or user-specific. If you specify y, key containers are computer-specific. If you specify n, key containers are user-specific. If neither y nor n is specified, this option displays the current setting.
`-o infile [outfile]`	Extracts the public key from the infile and stores it in a .csv file. A comma separates each byte of the public key. This format is useful for hard-coding references to keys as initialized arrays in source code. If you do not specify an outfile, this option places the output on the Clipboard. Note: This option does not verify that the input is only a public key. If the `infile` contains a key pair with a private key, the private key is also extracted.
`-p infile outfile [hashalg]`	Extracts the public key from the key pair in infile and stores it in outfile, optionally using the RSA algorithm specified by hashalg. This public key can be used to delay-sign an assembly using the /delaysign+ and /keyfile options of the Assembly Linker (Al.exe). When an assembly is delay-signed, only the public key is set at compile time and space is reserved in the file for the signature to be added later, when the private key is known.
`-pc container outfile [hashalg]`	Extracts the public key from the key pair in container and stores it in outfile. If you use the hashalg option, the RSA algorithm is used to extract the public key.
`-Pb [y\|n]`	Specifies whether the strong-name bypass policy is enforced. If you specify y, strong names for full-trust assemblies are not validated when loaded into a full-trust AppDomain. If you specify n, strong names are validated for correctness, but not for a specific strong name. The StrongNameIdentityPermission has no effect on full-trust assemblies. You must perform your own check for a strong name match. If neither `y` nor `n` is specified, this option displays the current setting. The default is `y`. Note: On 64-bit computers, you must set this parameter in both the 32-bit and the 64-bit instances of Sn.exe.
`-q[uiet]`	Specifies quiet mode; suppresses the display of success messages.
`-R[a] assembly infile`	Re-signs a previously signed or delay-signed assembly with the key pair in infile. If -Ra is used, hashes are recomputed for all files in the assembly.
`-Rc[a] assembly container`	Re-signs a previously signed or delay-signed assembly with the key pair in container. If -Rca is used, hashes are recomputed for all files in the assembly.
`-Rh assembly`	Recomputes hashes for all files in the assembly.
`-t[p] infile`	Displays the token for the public key stored in infile. The contents of infile must be a public key previously generated from a key pair file using -p. Do not use the -t[p] option to extract the token directly from a key pair file. Sn.exe computes the token by using a hash function from the public key. To save space, the common language runtime stores public key tokens in the manifest as part of a reference to another assembly when it records a dependency to an assembly that has a strong name. The -tp option displays the public key in addition to the token. If the AssemblySignatureKeyAttribute attribute has been applied to the assembly, the token is for the identity key, and the name of the hash algorithm and the identity key is displayed. Note that this option does not verify the assembly signature and should not be used to make trust decisions. This option only displays the raw public key token data.
`-T[p] assembly`	Displays the public key token for
