ssl - Linphone Android: TLS Handshake Error with Self Signed Certificate -

-

i'm trying use self-signed certificate configure tls in linphone android able communicate freeswitch sip server. ssl handshake fails following errors:

channel [0x9ec3c000]: ssl handshake failed : x509 - certificate verification failed, e.g. crl, ca or signature check failed cannot connect [tls://52.3.207.224:5061]

can please suggest what's way forward debug issue? or how can configure self-signed certificate in linphone android.

note: don't want disable tls server certificate verification suggested below

[sip] verify_server_certs=0

it because self-signed cert can not recognized third-party cas official linphone app pre-configured.

linphone uses it's own root ca store list server-cert going verified used linphone when received cert sip server.

if don't want disable server cert verification (it's avoid man-in-the-middle attack), , since there no ca linphone pre-configured can verify cert, you must create own ca , add linphone's ca list.

you can find ca list in linphone android source: res/raw/rootca.pem add ca , recompiled.

i'm not familiar linphone, think way go.

some useful links:

creating own ssl certificate authority (and dumping self signed certs)

using self-signed certs android linphone

i have data grid rows represent theta (0, pi) , columns represent phi (0, 2*pi) , f(theta,phi) density of dark matter @ location. wanted calculate power spectrum , have decided use healpy. what can not understand how format data healpy use. if provide code (in python obvious reasons) or point me tutorial, great! have tried hand @ doing following code: #grid dimensions nrows*ncols (subject change) theta = np.linspace(0, np.pi, num=grid.shape[0])[:, none] phi = np.linspace(0, 2*np.pi, num=grid.shape[1]) nside = 512 print "pixel area: %.2f square degrees" % hp.nside2pixarea(nside, degrees=true) pix = hp.ang2pix(nside, theta, phi) healpix_map = np.zeros(hp.nside2npix(nside), dtype=np.double) healpix_map[pix] = grid but, when try execute code power spectrum. specifically, : cl = hp.anafast(healpix_map[pix], lmax=1024) i error: typeerror: bad number of pixels if point me tutorial or edit code great. more specifications: data in 2d np array , can change numrows/...
