Add utility to convert JWKs to / from std Java keys in java.security.interfaces

[Vladimir Dzhuvinov]

Possible uses:

• Convert between JWK sets and Java keystore keys.
• Pass key args to crypto providers as JWKs.

The std Java key interfaces defined in java.security.interfaces:

ECKey
ECPrivateKey
ECPublicKey
RSAKey
RSAMultiPrimePrivateCrtKey
RSAPrivateCrtKey
RSAPrivateKey
RSAPublicKey

[Justin Richer]

I think these should be handled by the JWK classes themselves. I'll add a branch that implements this.

[Vladimir Dzhuvinov]

Good idea, and will fit solution 1 nicely (else we'll need to use full class names to prevent collision with java.security.interfaces.ECPublicKey and java.security.interfaces.RSAPublicKey).

How about

toECPublicKey()
toECPrivateKey()
toKeyPair()

resp.

toRSAPublicKey()
toRSAPrivateKey()
toKeyPair()

?

[Justin Richer]

Looks good to me.

Proposed solution pushed into branch native-keys.

Handles RSA keys in and out, symmetric keys outbound, and has unimplemented stubs for EC keys. Does not handle RSA CRT-formatted keys yet.

[Vladimir Dzhuvinov]

To generate the Java representations of the public + private ECKeys we'll need to lookup or hardwire the P curve constants defined in fips_186-3.pdf, page 89.

Added CRT support to RSAKey.toRSAPrivateKey() in commit 9449eaa.

With that the RSAKey class covers all required java.security imports + exports, JUnit tests still need to be written though :)

[Vladimir Dzhuvinov]

RSA key import / export completely covered now.

[Justin Richer]

RSA and octet keys covered, moving EC to a new issue
