Generate an ECDSA SSH keypair with a 521 bit private key. Ssh-keygen -t ecdsa -b 521 -C 'ECDSA 521 bit Keys' Generate an ed25519 SSH keypair- this is a new algorithm added in OpenSSH.

This depends on which key pair you are generating. When generating a CA in EJBCA up to three keys and certificates are generated: A CA signing keypair and certificate; An encryption keypair, used for encrypting keyrecovery information; An OCSP signer keypair and certificate; When using ECDSA keys, the CA signing keypair and the OCSP signer keypair will be the ECDSA keytype you select when creating the CA. When generating a CA in EJBCA, up to three keys and certificates are generated: A CA signing keypair and certificate; An encryption keypair, used for encrypting key recovery information; An OCSP signer keypair and certificate; When using ECDSA keys, the CA signing keypair and the OCSP signer keypair will be the ECDSA keytype you select when creating the CA.

Ejbca Generate Ecdsa Public Key Certificate

Install OpenSSL. When the executable in your path, enter this command to generate a private key: openssl ecparam -genkey -name secp256k1 -noout -out myprivatekey.pem To create the corresponding public key, do this: openssl ec -in myprivatekey.pem -pubout -out mypubkey.pem This will give you both keys in PEM format. The sequence in the holder reference of EAC CVC certificates should identify a public key. For CAs created and managed by EJBCA this sequence is normally an automatic property in the CA token. It starts with 00001 and is increased when new keys are generated (renew CA with checkbox to renew keys.

Definition

Ejbca Generate Ecdsa Public Key West

Creates a new instance of an implementation of the Elliptic Curve Digital Signature Algorithm (ECDSA).

Overloads

Creates a new instance of the default implementation of the Elliptic Curve Digital Signature Algorithm (ECDSA).

Returns

A new instance of the default implementation (ECDsaCng) of this class.

Creates a new instance of the default implementation of the Elliptic Curve Digital Signature Algorithm (ECDSA) with a newly generated key over the specified curve.

Parameters

Returns

A new instance of the default implementation (ECDsaCng) of this class.

See also

Creates a new instance of the default implementation of the Elliptic Curve Digital Signature Algorithm (ECDSA) using the specified parameters as the key.

Parameters

parameters

ECParameters

The parameters representing the key to use.

Returns

A new instance of the default implementation (ECDsaCng) of this class.

See also

Creates a new instance of the specified implementation of the Elliptic Curve Digital Signature Algorithm (ECDSA).

Parameters

algorithm

String

The name of an ECDSA implementation. The following strings all refer to the same implementation, which is the only implementation currently supported in the .NET Framework:

• 'ECDsa'

• 'ECDsaCng'

• 'System.Security.Cryptography.ECDsaCng'

You can also provide the name of a custom ECDSA implementation.

Returns

A new instance of the specified implementation of this class. If the specified algorithm name does not map to an ECDSA implementation, this method returns null.

Exceptions

The algorithm parameter is null.

Remarks

If you develop your own implementation of an ECDsa object, you can use the Create(String) method overload to create a custom algorithm string that specifies your implementation.

If you specify a custom value for the algorithm parameter, the CryptoConfig object will use it to determine whether an ECDSA object can be created.

Applies to

EJBCA, is a free softwarepublic key infrastructure (PKI) certificate authority software package maintained and sponsored by the Swedishfor-profit company PrimeKey Solutions AB, which holds the copyright to most of the codebase. The project's source code is available under terms of the Lesser GNU General Public License.

Design[edit]

The system is implemented in Java EE and designed to be platform independent and fully clusterable,^[1] to permit a greater degree of scalability than is typical of similar software packages. Multiple instances of EJBCA are run simultaneously, sharing a database containing the current certificate authorities (CAs). This permits each instance of the software to access any CA. The software also supports the use of a hardware security module (HSM), which provides additional security. Larger-scale installations would use multiple instances of EJBCA running on a cluster, a fully distributed database on a separate cluster and a third cluster with HSMs keeping the different CA keys.

EJBCA supports many common PKI architectures^[2] such as all in a single server, distributed RAs and external validation authority. An example architecture is illustrated below.

Key features[edit]

Multiple CA instances[edit]

EJBCA supports running unlimited number of CAs and levels of CAs in a single installation. Build a complete infrastructure, or several, within one instance of EJBCA.

Online Certificate Status Protocol[edit]

For certificate validation you have the choice of using X.509 CRLs and OCSP (RFC6960).

Registration authority[edit]

The EJBCA software includes a separate registration authority (RA) front end that can run on the same instance as the CA or distributed as external RAs. Communication between the CA and the RA is only using outgoing network connections to insulate the CA from less trusted networks, where the RA is typically placed.

Multiple algorithms[edit]

/generate-a-rsa-key-pair.html. You can use all common, and some uncommon algorithms in your PKI. RSA, ECDSA and DSA, SHA-1 and SHA-2. Compliant with NSA Suite B Cryptography.

Different certificate formats[edit]

EJBCA support both X.509v3 certificates and Card Verifiable certificates (CVC BSI TR-03110). Certificates are compliant with all standards such as RFC5280, CA/Browser Forum, eIDAS, ICAO 9303, EAC 2.10 and ISO 18013 Amendment 2 eDL.

PKCS#11 HSMs[edit]

Using the standard PKCS 11 API you can use most PKCS#11 compliant HSMs to protect the CAs’ and OCSP responders’ private keys.

Many integration protocols and APIs[edit]

EJBCA was designed with integration in mind. Most standard protocols are supported, CMP, SCEP, EST, and ACME as well as web services. Using integration APIs it is possible to integrate EJBCA as a certificate factory, not exposing its native user interfaces.

High performance and capacity[edit]

You can build a PKI with capacity of issuing billions of certificates at a rate of several hundreds per second.
