openssl_get_curve_names — Gets list of available curve names for ECC
Gets the list of available curve names for use in Elliptic curve cryptography (ECC) for public/private key operations. The two most widely standardized/supported curves are prime256v1 (NIST P-256) and secp384r1 (NIST P-384).
| AES Symmetric Keysize (Bits) | RSA and DSA Keysize (Bits) | ECC Keysize (Bits) |
|---|---|---|
| 80 | 1024 | 160 |
| 112 | 2048 | 224 |
| 128 | 3072 | 256 |
| 192 | 7680 | 384 |
| 256 | 15360 | 512 |
