OpenSSL "ans1parse -in" - Parse DER File
How to parse a DER file using the OpenSSL "ans1parse" command?
✍: FYIcenter.com
You can parse a DER file with OpenSSL "ans1parse -inform DER -in" command
as shown in the test below, assuming we have some DER file created from the previous tutorial:
C:\Users\fyicenter>\local\openssl\openssl.exe OpenSSL> asn1parse -inform DER -in integer.der 0:d=0 hl=2 l= 2 prim: INTEGER :FF OpenSSL> asn1parse -inform DER -in ascii.der 0:d=0 hl=2 l= 12 prim: IA5STRING :Hello World! OpenSSL> asn1parse -inform DER -in utf8.der 0:d=0 hl=2 l= 12 prim: UTF8STRING :Hello World! OpenSSL> asn1parse -in time.der -inform DER 0:d=0 hl=2 l= 15 prim: GENERALIZEDTIME :20161231235959Z OpenSSL> asn1parse -inform DER -in numeric.der 0:d=0 hl=2 l= 7 prim: NUMERICSTRING :3.14159
To read the output of the OpenSSL "ans1parse" command, we need to understand the meaning of each output column:
⇒ OpenSSL "ans1parse -genconf" - Configuration File
⇐ OpenSSL "ans1parse -genstr" - Single Primitive Field DER File
