Class PGPKeyAccessDataFormat

  • All Implemented Interfaces:
    AutoCloseable, org.apache.camel.Service, org.apache.camel.ShutdownableService, org.apache.camel.spi.DataFormat, org.apache.camel.spi.DataFormatName, org.apache.camel.StatefulService, org.apache.camel.SuspendableService
    Direct Known Subclasses:
    PGPDataFormat

    public class PGPKeyAccessDataFormat
    extends org.apache.camel.support.service.ServiceSupport
    implements org.apache.camel.spi.DataFormat, org.apache.camel.spi.DataFormatName
    This PGP Data Format uses the interfaces PGPPublicKeyAccessor and PGPSecretKeyAccessor to access the keys for encryption/signing and decryption/signature verification. These interfaces allow caching of the keys which can improve the performance.

    If you want to provide the key access via keyrings in the format of a byte array or file, then you should use the class PGPDataFormat.

      • SIGNATURE_VERIFICATION_OPTION_OPTIONAL

        public static final String SIGNATURE_VERIFICATION_OPTION_OPTIONAL
        Signature verification option "optional": Used during unmarshaling. The PGP message can or cannot contain signatures. If it does contain signatures then one of them is verified. This is the default option.

        Constant Field Values
      • SIGNATURE_VERIFICATION_OPTION_REQUIRED

        public static final String SIGNATURE_VERIFICATION_OPTION_REQUIRED
        Signature verification option "required": Used during unmarshaling. It is checked that the PGP message does contain at least one signature. If this is not the case a PGPException is thrown. One of the contained signatures is verified.

      • setArmored

        public void setArmored​(boolean armored)
        Sets if the encrypted file should be written in ascii visible text (for marshaling).
      • getArmored

        public boolean getArmored()
      • setIntegrity

        public void setIntegrity​(boolean integrity)
        Whether or not to add an integrity check/sign to the encrypted file for marshaling.
      • getIntegrity

        public boolean getIntegrity()
      • setKeyUserid

        public void setKeyUserid​(String keyUserid)
        User ID, or more precisely user ID part, of the key used for encryption. See also #setKeyUserids(List).
      • getKeyUserid

        public String getKeyUserid()
      • getKeyUserids

        public List<String> getKeyUserids()
      • setKeyUserids

        public void setKeyUserids​(List<String> keyUserids)
        Keys User IDs, or more precisely user ID parts, used for determining the public keys for encryption. If you just have one User ID, then you can also use the method setKeyUserid(String). The User ID specified in setKeyUserid(String) and in this method will be merged together and the public keys which have a User ID which contain a value of the specified User IDs the will be used for the encryption. Be aware that you may get several public keys even if you specify only one User Id, because there can be several public keys which have a User ID which contains the specified User ID.
      • setSignatureKeyUserid

        public void setSignatureKeyUserid​(String signatureKeyUserid)
        Userid, or more precisely user ID part, of the signature key used for signing (marshal) and verifying (unmarshal). See also setSignatureKeyUserids(List).
      • getSignatureKeyUserid

        public String getSignatureKeyUserid()
      • getSignatureKeyUserids

        public List<String> getSignatureKeyUserids()
      • setSignatureKeyUserids

        public void setSignatureKeyUserids​(List<String> signatureKeyUserids)
        User IDs, or more precisely user ID parts, used for signing and verification.

        In the signing case, the User IDs specify the private keys which are used for signing. If the result are several private keys then several signatures will be created. If you just have one signature User ID, then you can also use the method setSignatureKeyUserid(String) or this method. The User ID specified in setSignatureKeyUserid(String) and in this method will be merged together and the private keys which have a User Id which contain one value out of the specified UserIds will be used for the signature creation. Be aware that you may get several private keys even if you specify only one User Id, because there can be several private keys which have a User ID which contains the specified User ID.

        In the verification case the User IDs restrict the set of public keys which can be used for verification. The public keys used for verification must contain a User ID which contain one value of the User ID list. If you neither specify in this method and nor specify in the method setSignatureKeyUserid(String) any value then any public key in the public key ring will be taken into consideration for the verification.

        If you just have one User ID, then you can also use the method setSignatureKeyUserid(String). The User ID specified in setSignatureKeyUserid(String) and in this method will be merged together and the corresponding public keys represent the potential keys for the verification of the message.

      • getProvider

        public String getProvider()
      • setProvider

        public void setProvider​(String provider)
        Java Cryptography Extension (JCE) provider, default is Bouncy Castle ("BC"). Alternatively you can use, for example, the IAIK JCE provider; in this case the provider must be registered beforehand and the Bouncy Castle provider must not be registered beforehand. The Sun JCE provider does not work.
      • getCompressionAlgorithm

        public int getCompressionAlgorithm()
      • setCompressionAlgorithm

        public void setCompressionAlgorithm​(int compressionAlgorithm)

      • getHashAlgorithm

        public int getHashAlgorithm()
      • setHashAlgorithm

        public void setHashAlgorithm​(int hashAlgorithm)
        Digest algorithm for signing (marshaling). Possible values are defined in HashAlgorithmTags. Default value is SHA1.
      • getAlgorithm

        public int getAlgorithm()
      • setAlgorithm

        public void setAlgorithm​(int algorithm)
        Symmetric key algorithm for encryption (marshaling). Possible values are defined in SymmetricKeyAlgorithmTags. Default value is CAST5.

        public void setPublicKeyAccessor​(PGPPublicKeyAccessor publicKeyAccessor)
      • setSecretKeyAccessor

        public void setSecretKeyAccessor​(PGPSecretKeyAccessor secretKeyAccessor)
      • getSignatureVerificationOption

        public String getSignatureVerificationOption()
      • isWithCompressedDataPacket

        public boolean isWithCompressedDataPacket()
      • setWithCompressedDataPacket

        public void setWithCompressedDataPacket​(boolean withCompressedDataPacket)
        Indicator that Compressed Data packet shall be added during encryption. The default value is true. If false then the compression algorithm (see setCompressionAlgorithm(int) is ignored.
      • getFileName

        public String getFileName()
        Returns the file name for the literal packet. Cannot be null .
      • setFileName

        public void setFileName​(String fileName)
        Sets the file name for the literal data packet. Can be overwritten by the header Exchange.FILE_NAME. The default value is "_CONSOLE". "_CONSOLE" indicates that the message is considered to be "for your eyes only". This advises that the message data is unusually sensitive, and the receiving program should process it more carefully, perhaps avoiding storing the received data to disk, for example.

        Only used for marshaling.

        Parameters:
        fileName -
        Throws:
        IllegalArgumentException - if fileName is null
