[Dina]

Need reviewers who've got about 2-3 hrs for the following:

Project REDD at http://cr.opensolaris.org/~dinak/red-rsa
which includes:
6816864 collect together padding methods used by PKCS#11
6650809 performance may benefit from having ECC factored into libsoftcrypto

(Please ignore the follow-on work currently in progress:
6249983 softtoken based RSA/DSA slow on Niagara
4705679 Kernel programming interface for some asymmetric crypto
         ignore usr/src/uts/common/crypto/io/{dsa,dh,ecc}
6704056 C_GenerateKeyPair() needs to support CKM_DSA_KEY_PAIR_GEN
         ignore usr/src/lib/pkcs11/pkcs11_kernel/common/kernelKeys.c
)


Thanks,
