Exporting a Certificate to a File
See also Importing a Certificate from a File.
If the certificate is in the key store, it can exported using keytool:
Here's an example of the text form of an exported certificate:
// This method writes a certificate to a file. If binary is false, the
// certificate is base64 encoded.
public static void export(java.security.cert.Certificate cert, File file, boolean binary) {
try {
// Get the encoded form which is suitable for exporting
byte[] buf = cert.getEncoded();
FileOutputStream os = new FileOutputStream(file);
if (binary) {
// Write in binary form
os.write(buf);
} else {
// Write in text form
Writer wr = new OutputStreamWriter(os, Charset.forName("UTF-8"));
wr.write("-----BEGIN CERTIFICATE-----\n");
wr.write(new sun.misc.BASE64Encoder().encode(buf));
wr.write("\n-----END CERTIFICATE-----\n");
wr.flush();
}
os.close();
} catch (CertificateEncodingException e) {
} catch (IOException e) {
}
}
// Export in binary
> keytool -storepass my-keystore-password -alias myalias -export -file outfilename.cer
// Export in text format
> keytool -storepass my-keystore-password -alias myalias -export -rfc -file outfilename.cer
