The RSA encryption standard. This standard defines mechanisms for encrypting and signing data using the RSA public
key system. Cipher sometimes uses PCKS#1 padding. |

Defines the Diffie-Hellman key agreement protocol. Allows two parties who have never exchanged anything before to
negotiate a common secret key to use for encrypted message exchanges. |

The password-based encryption standard (PBE). This describes a method to generate a Secret Key based on a password. |

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 |

|
The private-key information syntax standard. This defines a method to store Private Key Information. |
| PKCS#9 |
n/a |
n/a |
n/a |
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. |
| PKCS#10 |

|
The certification request syntax standard. This describes a syntax for certification requests. |
| PKCS#11 / CryptoKi |
|
|
|
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. |

The elliptic curve cryptography standard. This describes mechanisms to encrypt and sign data using elliptic curve
cryptography. |

The cryptographic token information format standard. This describes a standard for the format of cryptographic
credentials stored on cryptographic tokens. |
