gnu.javax.net.ssl.provider
Class GNUSecurityParameters

java.lang.Object
  gnu.javax.net.ssl.provider.GNUSecurityParameters

All Implemented Interfaces:: SecurityParameters

class GNUSecurityParameters
extends java.lang.Object
implements SecurityParameters

This class implements the SecurityParameters interface, using the GNU Crypto interface for ciphers and macs, and the JZlib package for record compression.

Method Summary

byte[] decrypt(byte[] fragment, ProtocolVersion version, ContentType type)
          Decrypt, verify, and decompress a fragment, returning the transformed fragment.

byte[] encrypt(byte[] buf, int off, int len, ContentType type)
          Compress, MAC, encrypt, and write a record.

int getFragmentLength()
          Returns the maximum size that plaintext fragments may be.

ProtocolVersion getVersion()
          Returns the version of texts being sent.

void reset()
          Set all crypto primitives to null, meaning that any calls to #encrypt(byte[],int,int,org.metastatic.jessie.provider.ContentType) or #decrypt(byte[],org.metastatic.jessie.provider.ProtocolVersion,org.metastatic.jessie.provider.ContentType) will perform the identity transformation.

void setDeflating(boolean deflate)
          Turns zlib deflating on or off.

void setFragmentLength(int fragmentLength)
          Sets the maximum size that plaintext fragments may be.

void setInCipher(java.lang.Object inCipher)
          Set the cipher used to decrypt incoming fragments.

void setInflating(boolean inflate)
          Turns zlib inflating on or off.

void setInMac(java.lang.Object inMac)
          Set the MAC used to verify incoming fragments.

void setOutCipher(java.lang.Object outCipher)
          Set the cipher used to encrypt outgoing fragments.

void setOutMac(java.lang.Object outMac)
          Set the MAC used to authenticating outgoinging fragments.

void setVersion(ProtocolVersion version)
          Sets the version of texts being sent.

private static void transformRC4(byte[] in, int off, int len, byte[] out, int outOffset, gnu.java.security.prng.IRandom random)
          Encrypt/decrypt a byte array with the RC4 stream cipher.
