- If the incoming mail feature is enabled, tokens are being sent with
outgoing mails. These tokens contains information about what type of
action is allow with such token (such as replying to a certain issue
ID), to verify these tokens the code uses the HMAC-SHA256 construction.
- The output of the HMAC is truncated to 80 bits, because this is
recommended by RFC2104, but RFC2104 actually doesn't recommend this. It
recommends, if truncation should need to take place, it should use
max(80, hash_len/2) of the leftmost bits. For HMAC-SHA256 this works out
to 128 bits instead of the currently used 80 bits.
- Update to token version 2 and disallow any usage of token version 1,
token version 2 are generated with 128 bits of HMAC output.
- Add test to verify the deprecation of token version 1 and a general
MAC check test.
(cherry picked from commit 9508aa7713)
minio/sha256-simd provides additional acceleration for SHA256 using
AVX512, SHA Extensions for x86 and ARM64 for ARM.
It provides a drop-in replacement for crypto/sha256 and if the
extensions are not available it falls back to standard crypto/sha256.

This PR adds support to process incoming emails to perform actions.
Currently I added handling of replies and unsubscribing from
issues/pulls. In contrast to #13585 the IMAP IDLE command is used
instead of polling which results (in my opinion 😉) in cleaner code.
Procedure:
- When sending an issue/pull reply email, a token is generated which is
present in the Reply-To and References header.
- IMAP IDLE waits until a new email arrives
- The token tells which action should be performed
A possible signature and/or reply gets stripped from the content.
I added a new service to the drone pipeline to test the receiving of
incoming mails. If we keep this in, we may test our outgoing emails too
in future.
