It seems to work, but not at all optimized for size. The extra copy of sha256 code need to be removed. The yescrypt code in libbb/yescrypt/* is adapted from libxcrypt-4.4.38 with minimal edits, hopefully making it easier to track backports by resetting the tree to this commit, then comparing changes in upstream libxcrypt to the tree. function old new delta blockmix_xor_save - 7050 +7050 static.blockmix_xor - 6475 +6475 blockmix - 3390 +3390 SHA256_Transform - 3083 +3083 yescrypt_kdf_body - 1724 +1724 PBKDF2_SHA256 - 1003 +1003 smix1 - 960 +960 yescrypt_r - 890 +890 salsa20 - 804 +804 smix - 790 +790 smix2 - 659 +659 blockmix_salsa8_xor - 601 +601 yescrypt_kdf - 479 +479 blockmix_salsa8 - 415 +415 Krnd - 256 +256 _HMAC_SHA256_Init - 213 +213 _SHA256_Update - 198 +198 _SHA256_Final - 195 +195 decode64_uint32 - 166 +166 encode64 - 153 +153 decode64 - 136 +136 libcperciva_HMAC_SHA256_Buf - 132 +132 SHA256_Pad_Almost - 131 +131 salsa20_simd_unshuffle - 101 +101 salsa20_simd_shuffle - 101 +101 yes_crypt - 90 +90 libcperciva_SHA256_Buf - 86 +86 crypt_make_rand64encoded - 85 +85 static.atoi64_partial - 77 +77 alloc_region - 72 +72 ascii64 - 65 +65 PAD - 64 +64 _HMAC_SHA256_Final - 55 +55 static.cpu_to_be32_vect - 51 +51 free_region - 47 +47 libcperciva_SHA256_Init - 37 +37 yescrypt_init_local - 34 +34 crypt_make_pw_salt 92 125 +33 initial_state - 32 +32 .rodata 105771 105803 +32 atoi64 - 25 +25 explicit_bzero - 22 +22 pw_encrypt 920 941 +21 yescrypt_free_local - 9 +9 crypt_make_salt 85 - -85 ------------------------------------------------------------------------------ (add/remove: 43/1 grow/shrink: 3/0 up/down: 31042/-85) Total: 30957 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
