How do I get a list of the possible ciphers that are installed on the system for use in ssl_cipher_list? -- They all have husbands and wives and children and houses and dogs, and you know, they've all made themselves a part of something and they can talk about what they do. What am I gonna say?

Short: See my last answer - secure is never a black or white decission. The chosen cypher will protect your traffic and its better than plain text. Long: The client negotiates the supported ciphers with the server and chooses one that fits for him. I *guess* that k9/anroid simply does not suppo

I've just done a test with K9 mail on Android 4.4.2 and this is what I see in the log: ECDHE-ECDSA-AES128-SHA (128/128 bits) But when using Thunderbird I see: ECDHE-ECDSA-AES128-GCM-SHA256 (128/128 bits) I'm happy that Thunderbird is using a secure cipher but is Android? Is ECDHE-ECDSA-AES12

Is this an improvement (or more secure) despite going from 256bits to 128bits? yes it is because AES-GCM is currently the best cipher suite while there is no point for AES256, if AES128 will fall then it likely affects AES256 too and according to Brcue Schneier years ago AES128 has even less prob
