默认情况下,openssl pkcs8 使用HMAC-SHA1 作为 PBKDF2 中的伪随机函数(PRF)。您可以使用 -v2prf 选项指定更强的哈希函数(比如 hmacWithSHA512)。 示例 openssl pkcs8 -topk8 -v2 aes256 -v2prf hmacWithSHA256 -iter 100000 \ -in FactTrust_Root_CA.key -out FactTrust_Root_CA_PKCS8_AES256.key 下...
(指定 -aes256 加密算法后,默认会使用 PBKDF2 函数,迭代次数为 2048次,伪随机算法为 hmacWithSHA256,并且 key size 默认为 2048 bit) 如果不是 PKCS#8 格式,则建议把私钥转换成 PKCS#8 格式,使用 openssl pkcs8 命令,它支持手动指定上述选项。 查看Key Size...

这还将尝试使用属性“fips=yes”获取 HMAC-SHA256 算法,并确保它成功返回。 int FIPS_mode(void) 如果当前的全局属性字符串包含属性“fips=yes”(或“fips”),则返回1,否则返回0。 我们可以检查当前是否有提供 FIPS 算法的 Provider 可用,并稍微以不同的方式处理。 int FIPS_self_test(void) 如果FIPS_...
In openssl speed, changed the default hash function used with hmac from md5 to sha256. The -verify option to the openssl crl and openssl req will make the program exit with 1 on failure. The d2i_ASN1_GENERALIZEDTIME(), d2i_ASN1_UTCTIME(), ASN1_TIME_check(), and related functions hav...
