negotiate a common secret key to use for encrypted message exchanges. |

The extended-certificate syntax standard. This is currently being phased out in favor of X509 v3. |
| PKCS#7 |

The cryptographic message syntax standard. This defines a generic syntax for messages which have cryptography
applied to it. Imported by a browser to add to list of trusted certificates or signing authorities. cacerts
is not in this format. |
| PKCS#8 |

This defines selected attribute types for use in other PKCS standards. Defines the field names for data in a
certificate the signing authority attests to, e.g. facsimileTelephoneNumber, stateOrProvinceName, iSDNAddress,
streetAddress, localityName, supportedApplicationContext surname, telephoneNumber, organizationName ,teletexTerminalIdentifier
physicalDeliveryOfficeName, telexNumber postalAddress, title, postalCode, x121Address, postOfficeBox. |

The cryptographic token interface standard. This defines a technology independent programming interface for
cryptographic devices such as smartcards. |
| PKCS#12 |

The personal information exchange syntax standard. This describes a portable format for storage and transportation
of user private keys, certificates etc. Where a developer stores his code signing keys. .keystore
is not in this format, though Java also supports PCKS#12 keystore format. |
