These files were encoded with the help of der-ascii. They can be decoded using:

go get github.com/google/der-ascii/cmd/der2ascii
der2ascii -i <filename> -o <filename>.ascii

New or modified der-ascii files can be encoded using:

go get github.com/google/der-ascii/cmd/ascii2der
ascii2der i <filename>.ascii -o <filename>
