PuTTYgen is a key generator tool for creating pairs of public and private SSH keys. It is one of the components of the open-source networking client PuTTY. Although originally written for Microsoft Windows operating system, it is now officially available for. Putty. PuTTYgen is an key generator tool for creating SSH keys for PuTTY. It is analogous to the ssh-keygen tool used in some other SSH implementations. The basic function is to create public and private key pairs. PuTTY stores keys in its own format in.ppk files. However, the tool can also convert keys to and from other formats.

Public Keys, Private Keys, and Certificates
When performing authentication, SSL uses a technique called public-key cryptography.
Before we start, be aware of the following terminology: A certificate contains a public key (and a bunch of other stuff that doesn’t matter in this context). A digital identity (or just identity for short) is the combination of a certificate and the private key that matches the public key in that certificate. You can deauthorize this computer by logging out with appc logout: Generating Developer Certificate and Private/Public Keys. [email protected] logged into organization qetestorgpreprodteam 100001710. I'm looking for a java library or code to generate certificates, public and private keys on the fly without to use third party programs (such as openssl). I think something that is doeing keytool+openssl but from Java code. Consider a java servlet based web application secured with ssl and client authentification.

Public-key cryptography is based on the concept of a key pair,which consists of a public key and a privatekey. Data that has been encrypted with a public key canbe decrypted only with the corresponding private key. Conversely,data that has been encrypted with a private key can be decrypted onlywith the corresponding public key.
The owner of the key pair makes the public key available toanyone, but keeps the private key secret.

A certificate verifies that anentity is the owner of a particular public key.
Certificatesthat follow the X.509 standard contain a data section and a signaturesection. The data section includes such information as:
The Distinguished Name of the entity that owns thepublic key
The Distinguished Name of the entity that issued thecertificate
The period of time during which the certificate isvalid
The public key itself
You can obtain a certificate from a Certificate Authority(CA) such as VeriSign. Alternately, you can createa self-signed certificate, in which the ownerand the issuer are the same.
Keys vary based on the operations they support. For example, you use public and private key pairs to perform asymmetric encryption, whereas you use symmetric keys to conduct symmetric encryption. Similarly, one key might work for a 1024-bit RSA algorithm, while another might be suitable for a 256-bit elliptic curve algorithm. To generate the public/private key pair, enter this in the Command Prompt: ssh-keygen At the first prompt, “Enter file in which to save the key,” press Enter to save it in the default location.
An organization that issues certificates can establish a hierarchyof CAs. The root CA has a self-signed certificate. Each subordinateCA has a certificate that is signed by the next highest CA in thehierarchy. A certificate chain isthe certificate of a particular CA, plus the certificates of any higherCAs up through the root CA.
