PEM_read_bio_PrivateKey()NULL如果私钥在ECB模式下由DES EDE加密,则返回.问题发生在EVP_DecryptFinal_ex():
4128:error:06065064:digital envelope routines:EVP_DecryptFinal_ex:bad decrypt:evp_enc.c:330:
如果在CBC模式下DES EDE对相同的私钥进行加密,则此功能正常.
我检查过,这个问题在openssl 0.9.8r/y版本(没有FIPS)上是可重现的.如果使用FIPS构建openssl,则不会发生此问题.
是什么导致这种行为？
谢谢!
有时候,由于乘法no-nan b和c,我得到了一个nan:
double a = b * c; //b = 0, c = 1024, a = nan
或者作为floor()的结果:
double a = floor(b); //b = 2024, a = nan
重复计算和使用sleep()可以防止出现此问题:
a = b * c; //a = nan
a = b * c; //a = 0
a = floor(b); //a = nan
a = floor(b); //a = 2024
sleep(1);
a = b * c; //a = 0
sleep(1);
a = floor(b); //a = 2024

srand ((unsigned) time (NULL));
while (1) {
int zipcode, temperature, relhumidity;
// Get values that will fool the boss
zipcode = within (100000);
temperature = within (215) - 80;
relhumidity = within (50) + 10;
