                                                                   java.security.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

Returns:

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

Throws:

java.io.IOException - If failed to parse the data

java.security.GeneralSecurityException - If failed to generate the keys

decodeECPrivateKeySpec

public static java.util.AbstractMap.SimpleImmutableEntry<java.security.spec.ECPublicKeySpec,java.security.spec.ECPrivateKeySpec> decodeECPrivateKeySpec(java.io.InputStream inputStream,
                                                                                                                                                        boolean okToClose)

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 AbstractMap.SimpleImmutableEntry of ECPublicKeySpec and ECPrivateKeySpec

Throws:

java.io.IOException - If failed to to decode the DER stream
