Question:

Chilkat 9.5.0.58 TLS 1.2 handshake failure

Aug 18 '16 at 12:44

Connection via TLS 1.2 with Cipher TLS_RSA_WITH_AES_128_CBC_SHA fails with handshake failure but is successful via TLS 1.1 with Cipher TLS_RSA_WITH_AES_128_CBC_SHA.

In the Chilkat log the only difference I can identify is that when attempting the TLS 1.2 the signaturesize: 132 and via TLS 1.1 the signaturesize: 128.
