When performing authentication, SSL uses a technique called public-key cryptography.

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. Openssl generate key and csr. 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:

If at all possible I would consider creating a new keystore in OpenSSL and new keys rather than trying to pry out the private key from the Java keystore. By opening the Java keystore and extracting the private key one is moving beyond the designed security features.

• The public key consists of the modulus n and the public (or encryption) exponent e. The private key consists of the modulus n and the private (or decryption) exponent d, which must be kept secret. P, q, and λ(n) must also be kept secret because they can be used to calculate d. The public modulus n can be computed as p × q.

Following steps are required for generating a public private keystore: Create a keystore for client and server. Export public certificate from keystores.

• The Distinguished Name of the entity that owns thepublic key

• 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.

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. hanns g hw191 drivers for mac A certificate chain isthe certificate of a particular CA, plus the certificates of any higherCAs up through the root CA.
