help with private keys (blocs) extraction from file
Hello,
I need to extract blocs (private keys) from a file so that each bloc gets extracted to a separate file (*.priv), on the fly
I started to fiddle with awk, without much luck so far....
A block always has this pattern:
----- BEGIN CERTIFICATE -----
variable number of lines (never fixed, not known in advance)
----- END CERTIFICATE -----
The file could look like this :
----- BEGIN CERTIFICATE -----
zrzrfd
gdfgsgfhfgh
fghfg
fhfhhhhhhhhhhh
----- END CERTIFICATE -----
----- BEGIN CERTIFICATE -----
zerzrz
zerzrrruy
----- END CERTIFICATE -----
----- BEGIN CERTIFICATE -----
etuiyuvvvezrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrzfz
zrrrrrrrrr
zr
----- END CERTIFICATE -----
----- BEGIN CERTIFICATE -----
zerrrrrrrrrrrrrrrrrrrrrrrr
----- END CERTIFICATE -----
Thanks a ton in advance for any hints...

pkcs7
PKCS7(1) OpenSSL PKCS7(1)
NAME
pkcs7 - PKCS#7 utility
SYNOPSIS
openssl pkcs7 [-inform PEM|DER] [-outform PEM|DER] [-in filename] [-out filename] [-print_certs] [-text] [-noout] [-engine id]
DESCRIPTION
The pkcs7 command processes PKCS#7 files in DER or PEM format.
COMMAND OPTIONS
-inform DER|PEM
This specifies the input format. DER format is DER encoded PKCS#7 v1.5 structure.PEM (the default) is a base64 encoded version of the
DER form with header and footer lines.
-outform DER|PEM
This specifies the output format, the options have the same meaning as the -inform option.
-in filename
This specifies the input filename to read from or standard input if this option is not specified.
-out filename
specifies the output filename to write to or standard output by default.
-print_certs
prints out any certificates or CRLs contained in the file. They are preceded by their subject and issuer names in one line format.
-text
prints out certificates details in full rather than just subject and issuer names.
-noout
don't output the encoded version of the PKCS#7 structure (or certificates is -print_certs is set).
-engine id
specifying an engine (by it's unique id string) will cause req to attempt to obtain a functional reference to the specified engine,
thus initialising it if needed. The engine will then be set as the default for all available algorithms.
EXAMPLES
Convert a PKCS#7 file from PEM to DER:
openssl pkcs7 -in file.pem -outform DER -out file.der
Output all certificates in a file:
openssl pkcs7 -in file.pem -print_certs -out certs.pem
NOTES
The PEM PKCS#7 format uses the header and footer lines:
-----BEGIN PKCS7-----
-----END PKCS7-----
For compatibility with some CAs it will also accept:
-----BEGIN CERTIFICATE-----
-----END CERTIFICATE-----
RESTRICTIONS
There is no option to print out all the fields of a PKCS#7 file.
This PKCS#7 routines only understand PKCS#7 v 1.5 as specified in RFC2315 they cannot currently parse, for example, the new CMS as
described in RFC2630.
