/*
|
||||
* Heads up: CTR is a *family* of modes, because the "counter" function is
|
||||
* implementation-defined. This makes interoperability a pain in the neurons.
|
||||
* Here are several contradicting(!) interpretations:
|
||||
*
|
||||
* "The counter can be *any function* which produces a sequence which is
|
||||
* guaranteed not to repeat for a long time, although an actual increment-by-one
|
||||
* counter is the simplest and most popular."
|
||||
* The illustrations show that first increment should happen *after* the first
|
||||
* round. I call this variant BIGINT_INCR_0.
|
||||
* The AESAVS goes a step further and requires only that "counters" do not
|
||||
* repeat, leaving the method of counting completely open.
|
||||
* See: https://en.wikipedia.org/wiki/Block_cipher_mode_of_operation#Counter_(CTR)
|
||||
* See: https://csrc.nist.gov/csrc/media/projects/cryptographic-algorithm-validation-program/documents/aes/aesavs.pdf
|
||||
*
|
||||
* BIGINT_INCR_0 is the behavior of the OpenSSL command "openssl enc -aes-128-ctr",
|
||||
* and the behavior of CRYPTO_ctr128_encrypt(). OpenSSL is not alone in the
|
||||
* assumption that BIGINT_INCR_0 is all there is; even some NIST
|
||||
* specification/survey(?) doesn't consider counting any other way.
|
||||
* See: https://github.com/openssl/openssl/blob/33388b44b67145af2181b1e9528c381c8ea0d1b6/crypto/modes/ctr128.c#L71
|
||||
* See: http://www.cryptogrium.com/aes-ctr.html
|
||||
* See: https://web.archive.org/web/20150226072817/http://csrc.nist.gov/groups/ST/toolkit/BCM/documents/proposedmodes/ctr/ctr-spec.pdf
|
||||
*
|
||||
* "[T]he successive counter blocks are derived by applying an incrementing
|
||||
* function."
|
||||
* It defines a *family* of functions called "Standard Incrementing Function"
|
||||
* which only increment the lower-m bits, for some number 0<m<=blocksize.
|
||||
* The included test vectors suggest that the first increment should happen
|
||||
* *after* the first round. I call this INT32_INCR_0, or in general INTm_INCR_0.
|
||||
* This in particular is the behavior of CRYPTO_ctr128_encrypt_ctr32() in OpenSSL.
|
||||
* See: https://nvlpubs.nist.gov/nistpubs/Legacy/SP/nistspecialpublication800-38a.pdf
|
||||
* See: https://github.com/openssl/openssl/blob/33388b44b67145af2181b1e9528c381c8ea0d1b6/crypto/modes/ctr128.c#L147
|
||||
*
|
||||
* The python package "cryptography" and RFC 3686 (which appears among the
|
||||
* first online search results when searching for "AES CTR 128 test vector")
|
||||
* share a peculiar interpretation of CTR mode: the counter is incremented *before*
|
||||
* the first round. RFC 3686 does not consider any other interpretation. I call
|
||||
* this variant BIGINT_INCR_1.
|
||||
* See: https://tools.ietf.org/html/rfc3686.html#section-6
|
||||
* See: https://cryptography.io/en/latest/development/test-vectors/#symmetric-ciphers
|
||||
*
|
||||
* And finally, because the method is left open, a different increment could be
|
||||
* used, for example little endian, or host endian, or mixed endian. Or any crazy
|
||||
* LSFR with sufficiently large period. That is the reason for the constant part
|
||||
* "INCR" in the previous counters.
|
||||
*
|
||||
* Due to this plethora of mutually-incompatible counters,
|
||||
* the method of counting should be a template parameter.
|
||||
* This currently implements BIGINT_INCR_0, which means perfect
|
||||
* interoperability with openssl. The test vectors from RFC 3686 just need to be
|
||||
* incremented by 1.
|
||||
* TODO: Implement other counters?
