About this certificate

I hope this certificate review is providing you the detailed information in a simple form you where looking for.


We have idenified some issues with this certificate:
  • KeyUsage contains an inefficient encoding wherein the number of 'unused bits' is declared to be 5, but it should be 7. Raw Bytes: [3 2 5 128], Raw Binary: [00000011 00000010 00000101 10000000] RFC 5280 Section 4.2.1.3 describes the value of a KeyUsage to be a DER encoded BitString, which itself defines that all trailing 0 bits be counted as being "unused". (Where ITU-T Rec. X.680 | ISO/IEC 8824-1, 21.7, applies, the bitstring shall have all trailing 0 bits removed before it is encoded.)
  • Subscriber Certificate: commonName is deprecated. (BRs: 7.1.4.2.2)
