Structs§

check_range_n: Checks that the argument, as little-endian integer, is a reduced non-zero element of the scalar field.
check_range_p: Checks that the argument, as little-endian integer, is a reduced element of the base field.
convert_endianness: Converts endianness by reversing the input value.
ecdh_calc_shared_secret: Generates the shared secret according to the ECDH standard.
keygen: Calculates the public key from a given private key for use by either ECDSA or ECDH.
octet_string_to_point: Decodes a point according to the three encodings above.
point_to_octet_string_compressed: Compressed encoding
point_to_octet_string_hybrid: Hybrid encoding
point_to_octet_string_uncompressed: Uncompressed encoding
scalarmult_base: Raw scalar multiplication by the base point of the elliptic curve.
scalarmult_generic: Raw scalar multiplication by any point on the elliptic curve.
sign: Creates an ECDSA signature.
sign_step1: Creates an ECDSA signature, using a two-step procedure.
sign_step2: Second step of creating an ECDSA signature, using a two-step procedure.
verify: Verifies an ECDSA signature.
