Generating a CSR from python using sh

csr_creation.py

def generate_csr(domain):
    import tempfile
    import shutil
    from sh import openssl

    csr_data = "/C=%s/ST=%s/L=%s/O=%s/CN=www.%s" % (
        domain.country.upper(),
        domain.full_state,
        domain.city,
        domain.letterhead_name,
        domain.name,
    )

    temp_dir = tempfile.mkdtemp(dir=settings.DATA_DIR)
    csr_file = os.path.join(temp_dir, domain.name + '.csr')
    key_file = os.path.join(temp_dir, domain.name + '.key')
    open(key_file, 'w').write(domain.ssl_cert_key)
    openssl.req(
        '-new',
        '-key', key_file,
        '-out', csr_file,
        '-subj', csr_data,
    )
    domain.ssl_csr = open(csr_file).read()
    shutil.rmtree(temp_dir)
    if os.path.exists(key_file):
        raise Exception("The private key %s was not deleted!" % key_file)

how do i use this code, what library i need to import. we just need to pass domain name to it.

@ronak2303 This gist requires both the sh library, as well as a local installation of the openssl CLI.
