Transgui: TLS on MacOS is broken

[PeterDaveHello]

Hi there,

Thanks a lot for this awesome tool, it helps a lot!

I just found a small issue here, the release for MacOS seems to use SSLv3 to communicate with my server which is https enabled with TLS support but SSLv3 disabled for security reason, this problem doesn't exist on my Windows client, they are both v5.6, the error message is captured as below, please let me know that if there is anything I can do to help locate the problem, thanks!

PS:
My MacOS version: 10.12.5

Try to apply this patch.

@k0ste any chance to send a pull request so that the official build can include it? Thanks a lot.

I can easy make PR, but this patch should be reviewed, may be by @leonsoft-kras. Because this is hack, actually I'm not sure of its correctness.

I suggest in the ini-file to create a key for enabling / disabling protocols.
It's better than generally removing the support for other versions of the protocols.
Someone will approach one option, someone else.

I can not verify this code. For macos especially.
If this change is good - this setting can be made in the program settings

[PeterDaveHello]

As SSL was confirmed not secured anymore for a while, I'll respectfully suggested to just remove it, no matter which OS is using, the options can be prepared for TLS v1.0~v1.3 only, thanks!

[leonsoft-kras]

Removed support for SSL2, SSL3 as unsafe.
thanks!

[PeterDaveHello]

Thanks @leonsoft-kras, may I ask if there is any plan on the next release?

[leonsoft-kras]

There are minor problems with Linux and it seems like a switch to Lazarus 1.6.4.
I hope that soon.

[leonsoft-kras]

Please see Issue #962

[PeterDaveHello]

Should be fixed in #963

[PeterDaveHello]

Still not working yet.

[leonsoft-kras]

I now corrected the history file and the project file in version 5.8 (in several places it was necessary to write about version 5.8). Version for Windows already with the fix.

[PeterDaveHello]

@leonsoft-kras I'll build Raspberry Pi and Linux i386 release soon, MacOS release still has problem with TLS support however.

[leonsoft-kras]

This problem exists only in MacOS or is it still common for any operating system?

[PeterDaveHello]

I think it's Mac only.

[PeterDaveHello]

It's working on macOS 10.13, so maybe it's a bug from os or other level.
