Class SSLContext

  COM.claymoresystems.sslg.SSLContextInt
      COM.claymoresystems.ptls.SSLContext

public class SSLContext

extends SSLContextInt

SSLContext holds all state relevant to more than one SSL Session/ Connection. In particular, it's the access point for user keying material, user policy settings, and the session cache.

For clients, it is legal to merely create an SSLContext and use it immediately, though it is advisable to set the SSLPolicy.

Since servers must have keying material to operate, all SSLContexts which are to be used for servers must be initialized using loadEAYKeyFile() or loadPKS12KeyFile().

Currently, SSLContext supports only one key at a time and loading a new keyfile overrides any exiting keys/certificates. Future implementations may support multiple keys automatically selected based on the cipherSuite.

loadEAYKeyFile

public void loadEAYKeyFile(java.lang.String path,
                           java.lang.String passphrase)
                    throws java.io.FileNotFoundException,
                           java.io.IOException

Load a subset of SSLeay keyfiles.

We assume that the first key is bound to the first group of certificates

We assume that any certificates we find are strictly ordered from the user's certificate to the root.

Specified by:

loadEAYKeyFile in class SSLContextInt

Parameters:

path - the filename for the fiel

passphrase - the passphrase needed to decrypt the private key

Throws:

java.io.IOException - if the keyfile is badly formatted

java.io.FileNotFoundException - if the keyfile doesn't exist

loadEAYKeyFile

public void loadEAYKeyFile(java.io.InputStream is,
                           java.lang.String passphrase)
                    throws java.io.IOException

Load a subset of SSLeay keyfiles.

We assume that the first key is bound to the first group of certificates

We assume that any certificates we find are strictly ordered from the user's certificate to the root.

Specified by:

loadEAYKeyFile in class SSLContextInt

Parameters:

is - the file

passphrase - the passphrase needed to decrypt the private key

Throws:

java.io.IOException - if the keyfile is badly formatted
