我在Android中遇到了Keystores的问题。
我试图将android中的客户端连接到java中的服务器。我的代码适用于Android的15到22的API,但不适用于新的API 23更新:
我在Android客户端上遇到错误:
javax.net.ssl.SSLHandshakeException: Handshake failed
并且服务器上出现此错误:
javax.net.ssl.SSLHandshakeException: no cipher suites in common
这是我的代码,它在API 22或之前运行良好:
在客户端中,R.raw.publickey是公共.bks证书,而R.raw.publickey_v1是.bks的旧版本,用于与API 15兼容。

非常感谢你的帮助!
答案 0 :(得分:0)
我终于设法做到了......
错误是Android 6.0不再支持SHA-1。
错误是如此奇怪,我没有设法直接看到它......
对于与我有相同错误的人,只需使用SHA-256 ...
重新创建证书
