When I have developed it last year, I wanted to create the ECC key in the Android Keystore. Unfortunately, this ECC key is used to generate a session key thanks to ECDH, and ECDH is not supported by Android Keystore (this is what I have been said here: ECDH with key in Android Key Store ).

Apache: Create ECC CSR and Install ECC SSL Certificate Creating an ECC CSR and installing your SSL certificate on your Apache server Before generating an ECC CSR (Elliptic Curve Cryptography Certificate Signing Request) and ordering an ECC SSL Certificate form DigiCert, make sure that your environment is compatible with ECC SSL Certificates.

The Generate ECC Key Pair (OPM, QC3GENECC; ILE, Qc3GenECCKeyPair) API generates a random ECC key pair given a set of domain parameters to be used with elliptic curve cryptographic. Reasons for importing keys include wanting to make a backup of a private key (generated keys are non-exportable, for security reasons), or if the private key is provided by an external source. This document will guide you through using the OpenSSL command line tool to generate a key pair which you can then import into a YubiKey. I've seen various references on the web for generating Elliptic Curve KeyPairs in Java, and the two most commonly referenced examples (unsurprisingly) use the JDK default provider and BouncyCastle. But what confuses me is that the JDK default provider supports a single KeyPairGenerator algorithm name of EC while BouncyCastle also supports that as well as two additional distinct algorithm.

To sign an assembly with a strong name, you must have a public/private key pair. This public and private cryptographic key pair is used during compilation to create a strong-named assembly. You can create a key pair using the Strong Name tool (Sn.exe). Key pair files usually have an .snk extension.

Note

In Visual Studio, the C# and Visual Basic project property pages include a Signing tab that enables you to select existing key files or to generate new key files without using Sn.exe. In Visual C++, you can specify the location of an existing key file in the Advanced property page in the Linker section of the Configuration Properties section of the Property Pages window. The use of the AssemblyKeyFileAttribute attribute to identify key file pairs was made obsolete beginning with Visual Studio 2005.

To create a key pair, at a command prompt, type the following command:

sn –k <file name>

In this command, file name is the name of the output file containing the key pair.

The following example creates a key pair called sgKey.snk.

If you intend to delay sign an assembly and you control the whole key pair (which is unlikely outside test scenarios), you can use the following commands to generate a key pair and then extract the public key from it into a separate file. First, create the key pair:

Next, extract the public key from the key pair and copy it to a separate file:

When signing an assembly with a strong name, the Assembly Linker (Al.exe) looks for the key file relative to the current directory and to the output directory. When using command-line compilers, you can simply copy the key to the current directory containing your code modules.

If you are using an earlier version of Visual Studio that does not have a Signing tab in the project properties, the recommended key file location is the project directory with the file attribute specified as follows:
