libssh mbedTLS ECDSA support ============================= When built with mbedTLS, libssh currently does not support ECDSA key comparison. Since the comparison function is used during the verification of publickey authentication requests a libssh server will not be able to deal with ECDSA keys. In general, if the ssh_key_cmp function is used with mbedTLS, ECDSA key comparison won't work. mbedTLS and libssh in multithreaded applications ================================================== To use libssh with mbedTLS in a multithreaded application, mbedTLS has to be built with threading support enabled. If threading support is not available and multi threading is used, ssh_init will fail. More information about building mbedTLS with threading support can be found in the mbedTLS documentation.
