md_size = EVP_MD_size(digest),SM2算法采用SM3算法,因此md_size等于32。 由此可知,sm2_plaintext_size函数中的overhead取值等于106(10+2*32+32)。 msg_len:整个加密后的数据长度,加密后的数据格式参见GM/T 0009-2012的7.2节“加密数据格式”: 这里,XCoordinate和YCoordinate是加密过程基于随机数计算出的椭圆...
md_size = EVP_MD_size(digest),SM2算法采用SM3算法,因此md_size等于32。 从上述2点可知,sm2_pIaintext_size函数中的overhead取值等于106(10+2*32+32)。这里的magic number 10背后有什么含义呢? 对于SM2密文,ASN.1包括5个Tag和5个Length,ASN.1编码引入的长度不小于10个字节。分析如下: ...
