X509 serial number using java
问题 I need to get some data from X509 certificate. If I open a certificate file in windows, its showing its serial number in this format. ex. 39 65 70 eb d8 9f 28 20 4e c2 a0 6b 98 48 31 0d The same data I am trying to obtain using java. After get it loaded, I use x509.getSerialNumber(); and result is : 76292708057987193002565060032465481997 So what is the difference between both of these ? I want the result as upper one. 回答1: Windows shows the hexadecimal representation of the serial number,
