aws_encryption_sdk.internal.crypto.elliptic_curve¶
Contains elliptic curve functionality.
Functions
|
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
