The wolfSSL lightweight SSL library has supported ECC (Elliptic curve cryptography) since version 2.4.6 in December of 2012. Currently wolfSSL supports the most common ECC curve type at each bit strength defined by the standard, including the following.
SECP160R1
SECP192R1 (also called PRIME192V1)
SECP224R1
SECP256R1 (also called PRIME256V1)
SECP384R1
SECP521R1
wolfSSL defaults to SECP256R1, as is suggested, and as other SSL implementations do. We would like to get our users’ and readers’ feedback on these supported ECC curves. Are there additional curves you would like to see added to wolfSSL? If so, please let us know at facts@wolfssl.com.
