AeadTestGroup

A test group for authenticated encryption with additional data.

Fields in AeadTestGroup are:

name	type	desc	enum
ivSize	int	The IV size in bits. All IV sizes are multiple of 8 bits.
keySize	int	the keySize in bits
tagSize	int	The expected size of the tag in bits. This is the size that should be used to initialize instance of the cipher. The actual tag in the test vector may have a different size. Such a test vector is always invalid and an implementation is expected to reject such tags. All tag sizes are multiples of 8 bits.
type	str	the type of the test	'AeadTest'
tests	List of AeadTestVector	a list of test vectors

AsnSignatureTestVector

A test vector with an ASN.1 encoded public key signature. For example, ECDSA and DSA signatures are a pair of integers (r,s). These integers can be encoded in different ways. A popular encoding is to represent the integers as an ASN Sequence. The expectation is that any library generates only DER encoded signatures. Some libraries are also strict in the sense that only DER encoded signautes are accepted. Other libraries accept some signatures where the pair (r,s) uses an alternative BER encoding assuming of course that the encoded (r,s) is valid.

Fields additional to the fields in TestVector are:

name	type	desc
msg	HexBytes	The message to sign
sig	Asn	An ASN encoded signature for msg

Used in DsaTestGroup, EcdsaTestGroup.

ct	HexBytes	the ciphertext including tag

Used in DaeadTestGroup.
