- => 06 0A 2B 06 01 04 01 81 9B 19 01 00
- >> TLV(tag-length-value) Example OID
- (06) Tag
- (0A) Length
- [2B] 1(iso).3(identified-organization) (in ASN.1 BER encoding, i.e. 1*40+3 = 0x2b)
- [06] 6(dod)

- OID Converter: OID encoder/decoder
- v1.3 - Matthias Gaertner 1999/2001 - Freeware
- ============================================================
- The OID converter is a handy little tool to convert ASN.1 OIDs from readable dotted decimal notation to binary hexadecimal Distinguished Encoding Rules (DER) representation and vice versa.
- If you're into x.509 certificates, this may be useful to you, too.
- Usage:
- OID [-c|-C] [-o] {-i|1.2.3.4}
- converts dotted form to ASCII HEX DER output.
- OID -x [-o] {-i|hex-digits}
- decodes ASCII HEX DER and gives dotted form.
