OpenSSL "ans1parse" - ASN.1 OBJECT IDENTIFIER Field Type
What is ASN.1 OBJECT IDENTIFIER field type? How to specify OBJECT IDENTIFIER field type in OpenSSL "asn1parse" command?
✍: FYIcenter.com
ASN.1 OBJECT IDENTIFIER field is a primitive field that can be used to store
an Object Identifier (OID) defined in the ASN.1 standard.
An OID has 3 equivalent values: short name, long name and numerical format.
For example, "CN", "commonName", and "2.5.4.3" are the same OID
to identify the common name of the subject in a certificate.
To use ASN.1 OBJECT IDENTIFIER field in OpenSSL "asn1parse" command, you need to remember the following rules:
Here are examples of using IA5STRING with the OpenSSL "asn1parse" command:
C:\Users\fyicenter>\local\openssl\openssl.exe OpenSSL> asn1parse -genstr OBJECT:CN 0:d=0 hl=2 l= 3 prim: OBJECT :commonName OpenSSL> asn1parse -genstr OBJECT:commonName 0:d=0 hl=2 l= 3 prim: OBJECT :commonName OpenSSL> asn1parse -genstr OBJECT:2.5.4.3 0:d=0 hl=2 l= 3 prim: OBJECT :commonName
