Artifact 451a9c002f714f629ef81c5fa0fb5bd2d330a5985e8272b8212acb936f53fb0f:

• File src/exceptions/OFReadOrWriteFailedException.m — part of check-in [112eb62f7b] at 2021-11-13 20:28:25 on branch trunk — Add OFSecureTransportTLSStream

  This implements OFTLSStream using Apple's Secure Transport. While Secure
  Transport is declared deprecated by Apple, Apple so far has failed to
  provide a suitable replacement. They recommend Network.framework as a
  replacement, however it can neither work on arbitrary sockets, nor can
  it do STARTTLS. (user: js, size: 1818) [annotate] [blame] [check-ins using]
