X509 Certificate Public Key Problem in Displaying - HELP
Hi all !
I am facing problem in displaying Public Key. When I
am pasring X509 certificate the Public Key is coming
as a very long String as as given in Format 1 below,
though it should come like as given in Format 2 below.
out.println(x509certificate.getPublicKey());
I am using Bouncy Castle API and after that only the
Public Key is coming like a long String. Please
advice.
I tried to convert the Public key into byte array then
to String, but it is showing junk charaters. The
encoding for Publick key is ASN.1 DER but its is
giving error.
I need your advice .. Please HELP.......!
byte buf [] =
x509certificate.getPublicKey().getEncoded();
String s = new String(buf, "UTF-8");
s= new String(s.getBytes("ISO8859_1"), "UTF-8");
out.println(s);
Format 1
RSA Public Key modulus:
