Hi Bin, The OpenSSL names for P-256 and P-384 are prime256v1 and secp384r1.

When I run the following command: % openssl ecparam -list_curves It lists ... secp192k1 : SECG curve over a 192 bit prime field secp224k1 : SECG curve over a 224 bit prime field secp224r1 : NIST/SECG curve over a 224 bit prime field secp256k1 : SECG curve over a 256 bit prime field secp384r1 : NIST/SECG curve over a 384 bit prime field secp521r1 : NIST/SECG curve over a 521 bit prime field ... "secp256k1" is supported but not "secp256r1". The later is standardized and required by Suite B. Is it not supported in openssl-1.0.1? Why "secp256k1" instead of "secp256r1"? Thanks, -binlu
