+# This is the element of a database of curve parameters. Items are indexed by their
+# human-friendly name, such as "P-256". The element has the following fields:
+#
+# - p               the prime number that defines the finite field for all modulo operations
+# - b               the constant in the Short Weierstrass curve equation (can be None)
+# - order           the number of elements in the group with the generator below
+# - Gx              the affine coordinate X of the generator point
+# - Gy              the affine coordinate Y of the generator point
+# - G               the generator, as an EccPoint object
+# - modulus_bits    the minimum number of bits for encoding the modulus p
+# - oid             an ASCII string with the registered ASN.1 Object ID
+# - context         a raw pointer to memory holding a context for all curve operations (can be None)
+# - canonical       the canonical name of the curve
+# - openssh         the ASCII string used in OpenSSH id files for public keys on this curve
+# - rawlib          the reference to the dynamic libary with the low-level functions
+# - validate        a function that raises an exception if the the input point is invalid
