Method Details

extractKeyPairs

public Collection<KeyPair> extractKeyPairs(SessionContext session,
 NamedResource resourceKey,
 String beginMarker,
 String endMarker,
 FilePasswordProvider passwordProvider,
 InputStream stream,
 Map<String,String> headers)
                                    throws IOException,
GeneralSecurityException

Specified by:

extractKeyPairs in class AbstractKeyPairResourceParser

Parameters:

session - The SessionContext for invoking this load command - may be null if not invoked within a session context (e.g., offline tool or session unknown).

resourceKey - A hint as to the origin of the text lines

beginMarker - The line containing the begin marker

endMarker - The line containing the end marker

passwordProvider - The FilePasswordProvider to use in case the data is encrypted - may be null if no encrypted

stream - The decoded data InputStream

headers - Any headers that may have been available when data was read

Returns:

The extracted KeyPairs - may be null/empty if none.

Throws:

IOException - If failed to parse the data

GeneralSecurityException - If failed to generate the keys

parseECKeyPair

public static KeyPair parseECKeyPair(InputStream inputStream,
 boolean okToClose)
                              throws IOException,
GeneralSecurityException

Throws:

IOException

GeneralSecurityException

parseECKeyPair

public static KeyPair parseECKeyPair(ECCurves curve,
 DERParser parser)
                              throws IOException,
GeneralSecurityException

Parameters:

curve - The curve represented by this data (in case it was optional and somehow known externally) if null then it is assumed to be part of the parsed data. then it is assumed to be part of the data.

parser - The DERParser for the data

Returns:

The parsed KeyPair

Throws:

IOException - If failed to parse the data

GeneralSecurityException - If failed to generate the keys

decodeECPrivateKeySpec

public static Map.Entry<ECPublicKeySpec,ECPrivateKeySpec> decodeECPrivateKeySpec(ECCurves curve,
 ASN1Object sequence)
                                                                          throws IOException

ASN.1 syntax according to RFC 5915 is:

 
 ECPrivateKey ::= SEQUENCE {
      version        INTEGER { ecPrivkeyVer1(1) } (ecPrivkeyVer1),
      privateKey     OCTET STRING,
      parameters [0] ECParameters {{ NamedCurve }} OPTIONAL,
      publicKey  [1] BIT STRING OPTIONAL
 }
 
 

ECParameters syntax according to RFC5480:

 
 ECParameters ::= CHOICE {
      namedCurve         OBJECT IDENTIFIER
      -- implicitCurve   NULL
      -- specifiedCurve  SpecifiedECDomain
 }
 
 

Parameters:

curve - The curve represented by this data (in case it was optional and somehow known externally) if null then it is assumed to be part of the parsed data.

sequence - The ASN1Object sequence containing the DER encoded data

Returns:

The decoded AbstractMap.SimpleImmutableEntry of ECPublicKeySpec and ECPrivateKeySpec

Throws:

IOException - If failed to to decode the DER stream
