Functions ¶
func GetNtpTime ¶
GetNtpTime 利用服务器返回的 t2, t3, 和本地的 t1, t4 校准时间 delt = ((t2-t1)+(t3-t4))/2 current = t4 + delt
func GetRandPrintString ¶
GetRandPrintString 获取随机可打印字符串
func GetRealTimeRetry ¶
GetRealTimeRetry 重试获取实际时间
func Rimp160 ¶
Rimp160 Returns hash: RIMP160( SHA256( data ) ) Where possible, using RimpHash() should be a bit faster
