To test platform potential specific code of e.g. the WebCrypto API
Testing on Windows would be nice too, but all browsers fail to fetch resources
from the web-test-runner server.
To have tests work Browserstack Safari (also below iOS 15), as the tests are run in an iframe,
rewriting localhost as hostname, making WebCrypto not available.
We keep HTTP for the non-browserstack tests so that in local testing,
generating self-signed certs is not required.
sop-openpgpjs did not correctly apply the `OPENPGPJS_PATH` env variable; as a result,
it did not actually test the code from either the PR and base branch, but always from
the hardcoded version bundled with it.
Breaking change: all functions taking streams as inputs will now require passing Web Streams in Node.js . If given a native `stream.Readable` input, they will throw. The browser build is unaffected by this change.
Utils to convert from and to Web Streams in Node are available from v17,
see https://nodejs.org/api/stream.html#streamreadabletowebstreamreadable-options .
Previously, we automatically converted between Node native streams and custom, Web-like Readable streams.
This led to occasional issues.
Recent Node.js seems to have dropped support for ripemd160.
Thus, properly check the availability of hashes before using them.
Also, add Node.js 18 to CI.
