assertion `left == right` failed

[a-kolechko]

If you have base64 private key with underscore or hyphen at the beginning, like _M7rji76yb8vSG7p4unMZ_cHUaiIyCvHX2ExpJoslvg, and create a builder with it, but without the first character (VapidSignatureBuilder::from_base64('M7rji76yb8vSG7p4unMZ_cHUaiIyCvHX2ExpJoslvg', &subscription_info), it's accepted as a valid key, but then app panics after trying to send a notification:

Looks like the underlying issue (a panicking From impl in generic_array 0.14.7) has been fixed upstream.

Also upstream, block-buffer has cut a release candidate that moves away from it in any case.

It'll just take a while to propagate up the dependency tree.

Some progress. The deepest path:

• generic-array v1
• block-buffer v0.11`
• digest v0.11
• elliptic-curve
• primeorder
• p256
