Age	Commit message (Collapse)	Author
2017-06-14	Tidy up new prime generation code.	Rob Austein

2017-06-14	Faster prime generation algorithm for RSA.	Rob Austein
	Algorithm suggested by a note in Handbook of Applied Cryptography, motivated by profiling of libtfm fp_isprime() function showing something close to 50% of CPU time spent running Montgomery reductions in the small primes test, before we even get to Miller-Rabin.
2017-05-23	"core" arguments have not been const since we switched to core_selector.	Rob Austein

2017-04-03	PKCS #8 code for RSA and ECDSA.	Rob Austein
	Compiles, not yet tested. Existing tests need conversion to PKCS #8 before we can do anything useful with this. Once everything uses PKCS #8 instead of algorithm-specific formats, we can revisit API issues like whether hal_rpc_pkey_load() should still be taking `type` and `curve` arguments.
2016-09-20	Clean up the defines around rpc client, software hash cores, etc.	Paul Selkirk

2016-07-05	Attempt to add resource management, for multiple cores of the same type.	Paul Selkirk
	Find a suitable core, and mark it busy. Don't forget to release it as soon as you're done. This has a knock-on effect of un-const'ing core arguments and struct fields in a lot of places, and it moves some core checks around.
2016-06-14	Add support for ModExpA7	Paul Selkirk

2016-06-13	Allow NULL der_len parameter in hal-rsa_private_key_to_der().	Rob Austein

2016-05-14	Trailing whitespace cleanup.	Rob Austein

2016-03-29	Client-side rsa and ecdsa need to call remote get_random.	Paul Selkirk

2015-12-23	RPC interface to TRNG and (incomplete) PIN code.	Rob Austein

2015-12-23	Software modexp() implementation didn't compile due to missing pro	Rob Austein
	forma hal_core_t* argument.
2015-12-22	Add ASN.1 support for public keys (X.509 SubjectPublicKeyInfo format).	Rob Austein

2015-12-21	Fix names of private key DER functions.	Rob Austein

2015-12-20	RPC server stuff mostly written. Compiles, not yet tested. RPC	Rob Austein
	public key extraction functions on hold pending ASN.1 cleanup.
2015-12-13	whack copyrights	Paul Selkirk

2015-10-04	Whack libhal API to use current configure_core_selector mechanism.	Rob Austein
	Compiles, not yet tested.
2015-10-03	Use initializers for automatic variables of type fp_int because it's a	Rob Austein
	bit more obvious when we've forgotten to do this than when we've forgotten to call fp_init() or memset(). Convert rsa.c to use the one-element-array idiom so we can get stop prefixing every bignum reference with "&".
2015-09-08	Merge branch 'master' into ecdsa	Rob Austein
	This required a bit of manual cleanup in hal.h, hash.c, and rsa.c. No intended changes to functionality provided by parent comments, just a few tweaks to track API changes beyond git's ken.
2015-09-06	Add ECPoint I/O functions. ASN.1 cleanup.	Rob Austein

2015-09-02	Still more const-ification.	Rob Austein

2015-09-02	Clean up excessively complicated handling of opaque types in hash and	Rob Austein
	RSA code; use simpler model (pointer to incomplete structure) used in ECDSA code. Refactor RSA code to use shared ASN.1 routines.
2015-07-14	Changes to support Pavel's ModExpS6 core.	Rob Austein

2015-07-01	Change default to use software modexp until we sort out performance	Rob Austein
	issues in ModExp core.
2015-06-24	Rework API for loading keys from components. Relax key size	Rob Austein
	constraints to allow any key size within our supported range, since hsmbully seems to want to twist this knob to every possible setting.
2015-06-21	libcryptech -> libhal, doh.	Rob Austein

2015-06-21	Add digest algorithm IDs.	Rob Austein

2015-06-19	Add methods to extract public components from an RSA key. Other minor	Rob Austein
	cleanup and commenting within RSA module.
2015-06-19	Add temporary workaround to let us use software ModExp when we're	Rob Austein
	testing other code and don't want to wait for the as-yet-unoptimized FPGA ModExp core.
2015-06-19	Add replacement for fp_exptmod() using our ModExp core, so we don't	Rob Austein
	drag in all of TFM's Montgomery just to support the Miller-Rabin test.
2015-06-18	Supply public exponent as bigendian byte string rather than unsigned	Rob Austein
	long, since that's the form we'll need for PKCS #11.
2015-06-18	Helps to set the return value when reading a key, doh.	Rob Austein

2015-06-18	Add RSA blinding.	Rob Austein

2015-06-18	Refactor CRT code into public API.	Rob Austein

2015-06-17	Debug RSA key generation.	Rob Austein

2015-06-17	RSA key generation and DER support.	Rob Austein

2015-06-17	RSA key generation. Compiles, not (yet) tested otherwise.	Rob Austein

2015-06-16	Refactor key loading code.	Rob Austein

2015-06-11	Debug modexp_fp() buffer handling. Add basic timing report.	Rob Austein
	Compensate for PyCrypto's weird inversion of p and q when calculating CRT coefficients, and add key the key components PyCrypto doesn't bother pre-calculating to our test data.
2015-06-11	First cut at RSA decryption/signature using the Chinese Remainder	Rob Austein
	Theorem. Not yet tested, and given the number of moving parts I would be astonished if this version actually worked, but it does compile. Added some timing code to tests/test-rsa.c so we can see whether this is doing anything useful once it does work.
