split (one-line) cert bundle into 2 file

Question

I have one RSA PRIVATE KEY and one CERTIFICATE in one line, and I have to split it to one .key and .crt file.

Is it possible with sed or/and awk?

EDI1: example (as you can see its literally one line)

Answer 1

delimiter='-{5}[^-]+-{5}'
key=1
crt=2

# get the key
grep -o -P "\\${delimiter}.*?${delimiter}" cert | cut -d $'\n' -f $key | fmt -w 64 > the.key

# get the certificate
grep -o -P "\\${delimiter}.*?${delimiter}" cert | cut -d $'\n' -f $crt | fmt -w 64 > the.crt

The output files are the.key and the.crt.

I assume your intention is that .key and .crt are extensions instead of hidden files.

Also, cert is the input file that contains the key and the certificate all in one line.

Answer 2

Using fmt -w 35 file where file is the single line file, will get it into the exact format that you show in the question. fmt is a simple text formatter that will fold long lines and fmt -w 35 would try to fold the lines in in the file to match 35 characters per line, but would not break apart words that are too long, which is what makes it work in this case.

The awk command

awk 'BEGIN { of="file.pem" } { print >of } /^-----END/ { of="file.crt" }'

would read this and output the first bit to file.pem and the second bit to file.crt. It does this by defining the variable of ("out file") at the start to the first filename, and then changing it to the second filename when a line matching the pattern ^-----END is found. All lines in the output from fmt are printed to whatever filename of happens to contain.

All together:

fmt -w 35 file |
awk 'BEGIN { of="file.pem" } { print >of } /^-----END/ { of="file.crt" }'
