aws_encryption_sdk.internal.crypto.elliptic_curve

Contains elliptic curve functionality.

Functions

generate_ecc_signing_key(algorithm)

Returns an ECC signing key.

aws_encryption_sdk.internal.crypto.elliptic_curve.int_from_bytes()

Return the integer represented by the given array of bytes.

bytes

Holds the array of bytes to convert. The argument must either support the buffer protocol or be an iterable object producing bytes. Bytes and bytearray are examples of built-in objects that support the buffer protocol.

byteorder

The byte order used to represent the integer. If byteorder is ‘big’, the most significant byte is at the beginning of the byte array. If byteorder is ‘little’, the most significant byte is at the end of the byte array. To request the native byte order of the host system, use `sys.byteorder’ as the byte order value.

signed

Indicates whether two’s complement is used to represent the integer.

aws_encryption_sdk.internal.crypto.elliptic_curve.generate_ecc_signing_key(algorithm)

Returns an ECC signing key.

Parameters

algorithm (aws_encryption_sdk.identifiers.Algorithm) – Algorithm object which determines what signature to generate

Returns

Generated signing key

Raises

NotSupportedError – if signing algorithm is not supported on this platform
