Description

We have found the issue, ios app library does not follow the standard when armoring the key.

The encoded output stream must be represented in lines of no more than 76 characters each. (including new line character)

tools.ietf.org/html/rfc4880#section-6.3

But their line length goes beyond it and is of 76 or 77 chars

That might be related to my issue (and other ones) : https://github.com/krzyzanowskim/ObjectivePGP/issues/158

The generated message has a line of 76 chars. But the underlying issue might be that the generated data is simply wrong.

[krzyzanowskim]

do you have an sample output to analyze, or code to reproduce what you say is happening?

For example:

-----BEGIN PGP PRIVATE KEY BLOCK-----
Version: ObjectivePGP
Comment: https://www.objectivepgp.com
Charset: UTF-8

As you can see, each line has 76 characters, while according to the requirements, there should be no more than 76 characters, including a new line.

Decoding software must ignore all white space.

newline shouldn't be a problem though
