Formatting a string to PEM with headers and line breaks
Hi,
I’m quite new in Elixir and I’m trying to format a string to a PEM format. I have the certificate value like MIIDBTCCAe2...... and I need to convert it to
-----BEGIN CERTIFICATE-----
MIIDBTCCAe2......
....
-----END CERTIFICATE-----
Is there any library function that would do that for me?
Would appreciate if you could help.
Thanks in advance

If the input string is a base64 encoded certificate, there is no need to add the PEM headers just so the PEM parser can strip them off again. Just use Base.decode64!/1 to get the binary (DER) certificate.
In other words:
[{:Certificate, der, :not_encrypted}] = :public_key.pem_decode("-----BEGIN CERTIFICATE-----\n#{cert}\n-----END CERTIFICATE-----\n")
and
der = Base.decode64!(cert)
are equivalent.
