PGP

Since Camel 2.9

The PGP Data Format integrates the Java Cryptographic Extension into Camel, allowing simple and flexible encryption and decryption of messages using Camel’s familiar marshal and unmarshal formatting mechanism. It assumes marshalling to mean encryption to ciphertext and unmarshalling to mean decryption back to the original plaintext. This data format implements only symmetric (shared-key) encryption and decryption.

PGPDataFormat Options

The PGP dataformat supports 14 options, which are listed below.

Name Default Java Type Description

Name	Default	Java Type	Description
keyUserid		`String`	The user ID of the key in the PGP keyring used during encryption. Can also be only a part of a user ID. For example, if the user ID is Test User then you can use the part Test User or to address the user ID.
signatureKeyUserid		`String`	User ID of the key in the PGP keyring used for signing (during encryption) or signature verification (during decryption). During the signature verification process the specified User ID restricts the public keys from the public keyring which can be used for the verification. If no User ID is specified for the signature verficiation then any public key in the public keyring can be used for the verification. Can also be only a part of a user ID. For example, if the user ID is Test User then you can use the part Test User or to address the User ID.
password		`String`	Password used when opening the private key (not used for encryption).
signaturePassword		`String`	Password used when opening the private key used for signing (during encryption).

Encrypting with PGPDataFormat

The following sample uses the popular PGP format for encrypting/decrypting files using the Bouncy Castle Java libraries:

The following sample performs signing + encryption, and then signature verification + decryption. It uses the same keyring for both signing and encryption, but you can obviously use different keys:

Or using Spring:

To work with the previous example you need the following

A public keyring file which contains the public keys used to encrypt the data
A private keyring file which contains the keys used to decrypt the data
The keyring password

Managing your keyring

To manage the keyring, I use the command line tools, I find this to be the simplest approach in managing the keys. There are also Java libraries available from http://www.bouncycastle.org/java.html if you would prefer to do it that way.

Install the command line utilities on linux

apt-get install gnupg

Create your keyring, entering a secure password

gpg --gen-key

If you need to import someone elses public key so that you can encrypt a file for them.

gpg --import <filename.key

The following files should now exist and can be used to run the example

ls -l ~/.gnupg/pubring.gpg ~/.gnupg/secring.gpg

PGP Decrypting/Verifying of Messages Encrypted/Signed by Different Private/Public Keys

A PGP Data Formater can decrypt/verify messages which have been encrypted by different public keys or signed by different private keys. Just, provide the corresponding private keys in the secret keyring, the corresponding public keys in the public keyring, and the passphrases in the passphrase accessor.

Map<String, String> userId2Passphrase = new HashMap<String, String>(2);
// add passphrases of several private keys whose corresponding public keys have been used to encrypt the messages
userId2Passphrase.put("UserIdOfKey1","passphrase1"); // you must specify the exact User ID!
userId2Passphrase.put("UserIdOfKey2","passphrase2");
PGPPassphraseAccessor passphraseAccessor = new PGPPassphraseAccessorDefault(userId2Passphrase);

PGPDataFormat pgpVerifyAndDecrypt = new PGPDataFormat();
pgpVerifyAndDecrypt.setPassphraseAccessor(passphraseAccessor);
// the method getSecKeyRing() provides the secret keyring as byte array containing the private keys
pgpVerifyAndDecrypt.setEncryptionKeyRing(getSecKeyRing()); // alternatively you can use setKeyFileName(keyfileName)
// the method getPublicKeyRing() provides the public keyring as byte array containing the public keys
pgpVerifyAndDecrypt.setSignatureKeyRing((getPublicKeyRing());  // alternatively you can use setSignatureKeyFileName(signatgureKeyfileName)
// it is not necessary to specify the encryption or signer  User Id

from("direct:start")
         ...
        .unmarshal(pgpVerifyAndDecrypt) // can decrypt/verify messages encrypted/signed by different private/public keys
        ...

The functionality is especially useful to support the key exchange. If you want to exchange the private key for decrypting you can accept for a period of time messages which are either encrypted with the old or new corresponding public key. Or if the sender wants to exchange his signer private key, you can accept for a period of time, the old or new signer key.
Technical background: The PGP encrypted data contains a Key ID of the public key which was used to encrypt the data. This Key ID can be used to locate the private key in the secret keyring to decrypt the data. The same mechanism is also used to locate the public key for verifying a signature. Therefore you no longer must specify User IDs for the unmarshaling.

Restricting the Signer Identities during PGP Signature Verification

If you verify a signature you not only want to verify the correctness of the signature but you also want check that the signature comes from a certain identity or a specific set of identities. Therefore it is possible to restrict the number of public keys from the public keyring which can be used for the verification of a signature.

Signature User IDs

// specify the User IDs of the expected signer identities
 List<String> expectedSigUserIds = new ArrayList<String>();
 expectedSigUserIds.add("Trusted company1");
 expectedSigUserIds.add("Trusted company2");

 PGPDataFormat pgpVerifyWithSpecificKeysAndDecrypt = new PGPDataFormat();
 pgpVerifyWithSpecificKeysAndDecrypt.setPassword("my password"); // for decrypting with private key
 pgpVerifyWithSpecificKeysAndDecrypt.setKeyFileName(keyfileName);
 pgpVerifyWithSpecificKeysAndDecrypt.setSignatureKeyFileName(signatgureKeyfileName);
 pgpVerifyWithSpecificKeysAndDecrypt.setSignatureKeyUserids(expectedSigUserIds); // if you have only one signer identity then you can also use setSignatureKeyUserid("expected Signer")

from("direct:start")
         ...
        .unmarshal(pgpVerifyWithSpecificKeysAndDecrypt)
        ...

If the PGP content has several signatures the verification is successful as soon as one signature can be verified.
If you do not want to restrict the signer identities for verification then do not specify the signature key User IDs. In this case all public keys in the public keyring are taken into account.

Several Signatures in One PGP Data Format

The PGP specification allows that one PGP data format can contain several signatures from different keys. Since Camel 2.13.3 it is possible to create such kind of PGP content via specifying signature User IDs which relate to several private keys in the secret keyring.

Several Signatures

 PGPDataFormat pgpSignAndEncryptSeveralSignerKeys = new PGPDataFormat();
 pgpSignAndEncryptSeveralSignerKeys.setKeyUserid(keyUserid); // for encrypting, you can also use setKeyUserids if you want to encrypt with several keys
 pgpSignAndEncryptSeveralSignerKeys.setKeyFileName(keyfileName);
 pgpSignAndEncryptSeveralSignerKeys.setSignatureKeyFileName(signatgureKeyfileName);
 pgpSignAndEncryptSeveralSignerKeys.setSignaturePassword("sdude"); // here we assume that all private keys have the same password, if this is not the case then you can use setPassphraseAccessor

 List<String> signerUserIds = new ArrayList<String>();
 signerUserIds.add("company old key");
 signerUserIds.add("company new key");
 pgpSignAndEncryptSeveralSignerKeys.setSignatureKeyUserids(signerUserIds);

from("direct:start")
         ...
        .marshal(pgpSignAndEncryptSeveralSignerKeys)
        ...

Support of Sub-Keys and Key Flags in PGP Data Format Marshaler

An OpenPGP V4 key can have a primary key and sub-keys. The usage of the keys is indicated by the so called Key Flags. For example, you can have a primary key with two sub-keys; the primary key shall only be used for certifying other keys (Key Flag 0x01), the first sub-key shall only be used for signing (Key Flag 0x02), and the second sub-key shall only be used for encryption (Key Flag 0x04 or 0x08). The PGP Data Format marshaler takes into account these Key Flags of the primary key and sub-keys in order to determine the right key for signing and encryption. This is necessary because the primary key and its sub-keys have the same User IDs.

Support of Custom Key Accessors

You can implement custom key accessors for encryption/signing. The above PGPDataFormat class selects in a certain predefined way the keys which should be used for signing/encryption or verifying/decryption. If you have special requirements how your keys should be selected you should use the PGPKeyAccessDataFormat class instead and implement the interfaces PGPPublicKeyAccessor and PGPSecretKeyAccessor as beans. There are default implementations DefaultPGPPublicKeyAccessor and DefaultPGPSecretKeyAccessor which cache the keys, so that not every time the keyring is parsed when the processor is called.

PGPKeyAccessDataFormat has the same options as PGPDataFormat except password, keyFileName, encryptionKeyRing, signaturePassword, signatureKeyFileName, and signatureKeyRing.

Dependencies

To use the PGP dataformat in your camel routes you need to add the following dependency to your pom.

<dependency>
  <groupId>org.apache.camel</groupId>
  <artifactId>camel-crypto</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>

Spring Boot Auto-Configuration

When using crypto with Spring Boot make sure to use the following Maven dependency to have support for auto configuration:

<dependency>
  <groupId>org.apache.camel.springboot</groupId>
  <artifactId>camel-crypto-starter</artifactId>
  <version>x.x.x</version>

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.
