2019-03-04Use the hashsig pseudorandom key generation method if the key is exportable.Paul Selkirk
2018-11-14Add some yields to hal_hashsig_ks_init, so other tasks can run while we're ↵Paul Selkirk
rebuilding the hash tree.
2018-08-12Clean up builds for *BSD/clang.Paul Selkirk
Move lm[ot]s_algorithm_t definitions to hal.h, prefix all public symbols with 'hal_'. Remove some unused functions. Wrap hal_pkey_slot_t initializers in an extra set of curly braces. Remove an unused-argument kludge (x=x;) because gcc doesn't care, and clang complains. Make timersub a proper macro. Add some casts to printf arguments, because !@#$ printf formats.
2018-07-24Change the rest of the hashsig ASN.1 wrapper functions to static inline, for ↵Paul Selkirk
consistency.
2018-07-24A recent(?) version of arm-none-eabi-gcc decided to make storage for enumsPaul Selkirk
the minimum size necessary, so hal_asn1_decode_lms_algorithm and hal_asn1_decode_lmots_algorithm were writing 4 bytes of data into 1-byte variables. Hilarity ensued. Yes, I already knew that conflating enum with uint32_t was a bad idea, I was just being lazy. For that matter, sizeof(size_t) isn't guaranteed either, although arm-none-eabi-gcc treats it as 32 bits on this 32-bit target (for now), so exercise proper data hygiene in hal_asn1_decode_size_t as well.

2018-05-01Add some yields to try to improve responsiveness during hashsig key ↵Paul Selkirk
generation and deletion.
2018-04-19Reconstruct the hashsig hash tree(s) on device restart.Paul Selkirk
2018-04-19Update to draft-10: clarifications and Test Case 2;Paul Selkirk
add ability to export public key to xdr for interop testing
2018-04-19For 2^w and 2^h, replace hard-coded w2 and h2 values with 1<<w and 1<<h.Paul Selkirk
2018-04-19Fold the coef* functions into a single function, because that really was ↵Paul Selkirk
premature optimization.
2018-04-19Fix coef4, which was swapping digitsPaul Selkirk
2018-04-19Implement hash-based signatures, per draft-mcgrew-hash-sigs-08.txtPaul Selkirk
