François-Simon Fauteux-Chapleau	792b851d77	dht_proxy_server: fix Android push notifications This commit updates the format of the push notification requests sent by the DHT proxy server to conform to FCM's HTTP v1 API. (The previously used API was deprecated in 2023, see: https://firebase.google.com/docs/cloud-messaging/migrate-v1) The "priority" and "ttl" (time to live) options are specific to Android and therefore need to be put in the "android" block, as documented here: https://firebase.google.com/docs/reference/fcm/rest/v1/projects.messages	2024-09-19 12:48:36 -04:00

Matthew Webb	76a2bd234a	Get off of deprecated GCM AES methods Multiple compiler warnings note that the gcm_aes_* family of functions are deprecated. They have been replaced with gcm_aes<key_length>_. This change uses the correct set of functions based on the given key size. Resolves #571. Sample compiler warning: /home/noviv/opendht/src/crypto.cpp: In function ‘dht::Blob dht::crypto::aesEncrypt(const uint8_t, size_t, const dht::Blob&)’: /home/noviv/opendht/src/crypto.cpp:97:20: warning: ‘void nettle_gcm_aes_set_key(gcm_aes_ctx, size_t, const uint8_t)’ is deprecated [-Wdeprecated-declarations] 97 \| gcm_aes_set_key(&aes, key.size(), key.data()); \| ^ In file included from /home/noviv/opendht/src/crypto.cpp:27: /usr/include/nettle/gcm.h:276:1: note: declared here 276 \| gcm_aes_set_key(struct gcm_aes_ctx *ctx, \| ^~~~~~~~~~~~~~~) https://github.com/gnutls/nettle/commit/6a19845e6f71791ca98765d490ec08e776494bee marked the functions as deprecated.	2024-07-11 10:07:05 -04:00
