AeadTestGroup

A test group for authenticated encryption with additional data.

Fields additional to the fields in TestGroup are:

name type desc
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    :

AeadTestVector

A test vector for authenticated encryption with additional data.

Fields additional to the fields in TestVector are:

name type desc
key HexBytes the key
iv HexBytes the nonce
aad HexBytes additional authenticated data
msg HexBytes the plaintext
ct HexBytes the ciphertext (without iv and tag)
tag HexBytes The authenticatian tag. Most encryption append the tag
: : : to the ciphertext. Encryption results in the :
 :          : concatenation ct || tag and decryption expects ct ||   :
 :          : tag as input. There are however some exceptions. For   :
 :          : example AEAD-AES-SIV-CMAC (RFC 5297) computes a        :
 :          : synthetic IV (SIV), which is used to initialize the    :
 :          : counter for AES. The typical encoding here is to       :
 :          : prepend the SIV. I.e. implementations would expect     :
 :          : ciphertext of the form tag || ct or iv || tag || ct.   :

Used in AeadTestGroup.

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

TestGroup

A test group contains a list of test vectors of the same type. The test group describes parameters that are common for all the test vectors. Often some parameters are given in multiple formats to simplify testing. For example, asymmetric private key are typically given in a raw format, PKCS #8 encoded and in PEM format. All fields in a test group are corretly formatted. Incorrectly formatted inputs are always in the test vectors. The list below describes the fields that are common to all test groups.

Fields additional to the fields in TestGroup are:

name type desc
tests List a list of test vectors
type str The type of the test vectors.
