Method Detail

extractKeyPairs

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

Specified by:

extractKeyPairs in class AbstractKeyPairResourceParser

Parameters:

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

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

decodeECPrivateKeySpec

public static Pair<ECPublicKeySpec,ECPrivateKeySpec> decodeECPrivateKeySpec(InputStream inputStream,
                                                                            boolean okToClose)
                                                                     throws IOException

ASN.1 syntax according to rfc5915 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:

inputStream - The InputStream containing the DER encoded data

okToClose - true if OK to close the DER stream once parsing complete

Returns:

The decoded Pair of ECPublicKeySpec and ECPrivateKeySpec

Throws:

IOException - If failed to to decode the DER stream

decodeECPrivateKeySpec

public static final ECPrivateKeySpec decodeECPrivateKeySpec(DERParser parser)
                                                     throws IOException

Throws:

IOException

decodeECPublicKeyValue

public static final ECPoint decodeECPublicKeyValue(ECCurves curve,
                                                   DERParser parser)
                                            throws IOException

ASN.1 syntax according to rfc5915 is:

      publicKey  [1] BIT STRING OPTIONAL
 

Parameters:

curve - The ECCurves curve

parser - The DERParser assumed to be positioned at the start of the data

Returns:

The encoded ECPoint

Throws:

IOException - If failed to create the point
