示例1: _openssl_get_supported_curves
# 需要導入模塊: from cryptography.hazmat.bindings.openssl import binding [as 別名]
# 或者: from cryptography.hazmat.bindings.openssl.binding import Binding [as 別名]

# Ed25519 and X25519 are always present in cryptography>=2.6
# The python cryptography lib provides a different interface for these curves,
# so they are handled differently in the ECDHPriv/Pub and EdDSAPriv/Pub classes
