Many tests in this package check the ASN.1 encoding for various kinds of parameters.  The openssl
command line tool can be used to view and encode data in ASN.1.

Test data for encoding tests is preceded by its definition in the OpenSSL generation string
format described at https://wiki.openssl.org/index.php/Manual:ASN1_generate_nconf(3).  To
reproduce the base64-encoded values in the test files, do:

# Put data definition in a file, eg input.cnf
openssl asn1parse -genconf input.cnf -out /tmp/asn1.der
openssl base64 -in /tmp/asn1.der

To view the ASN.1 data encoded in a base64-encoded string, do:

echo 'BASE64-ENCODED DATA HERE' | openssl asn1parse -i
