關(guān)閉掉一些不需要編譯的內(nèi)部算法源碼目錄可以：
具體辦法咏瑟，修改Configure檔案下的編譯目錄募疮，比如，只需要chacha20-poly1305：
# Top level directories to build
#$config{dirs} = [ "crypto", "ssl", "engines", "apps", "test", "util", "tools", "fuzz" ];
# crypto/ subdirectories to build
#$config{sdirs} = [
# "objects",
# "md2", "md4", "md5", "sha", "mdc2", "hmac", "ripemd", "whrlpool", "poly1305", "blake2", "siphash", "sm3",
# "des", "aes", "rc2", "rc4", "rc5", "idea", "aria", "bf", "cast", "camellia", "seed", "sm4", "chacha", "modes",

# Top level directories to build
$config{dirs} = [ "crypto"];
# crypto/ subdirectories to build
$config{sdirs} = [

如何裁減openssl庫常懷感恩之心——魯迅 常規(guī)編譯的openssl庫一般包含libssl和libcrypto兩個(gè)目標(biāo)庫文件毕籽，libssl.so通常為0.5M左右， libcrypto.so為2....
