About this certificate

This digital certificate with serial number f8:34:74:13:7e:0a:e4:2e:21:97:64:e7:86:1d:ca:a3 was issued on by Gandi.

This certificate has already expired and will cause a warning or error message in the browser it's still listed on this site to allow you to look back on previously issued certificates. If we have found any compliance issues with this certificate they will be shown below. 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)
