Based on Nekogram. Key additions: - Rebrand to FoxiGram (app name, APK name, applicationId com.foxigram.app) - Embedded Xray (VLESS+Reality) proxy client via JNI libxray.so - Bundled hidden one-tap proxies (LTE + WiFi), read-only in UI - Auto-restore proxy on restart, rebind to active network (LTE/WiFi) - Server credentials externalized to git-ignored XrayServers.java (+ template) - libxray Go source included; compiled .so, keystore, google-services.json ignored |

Choosing A Hash Function
Note: this document is still very much a work-in-progress. Currently missing:
- recommendations for hashed containers
- recommendations for a better persistent hash
- recommendations for a secure hash
If a hash function with unchanging output is needed, please select from one of the unchanging forever options below.
Non-cryptographic
| name | input | output | unchanging forever | notes |
|---|---|---|---|---|
Hash() |
overloaded | uint32_t |
no | This function is currently being updated to return size_t. |
PersistentHash() |
overloaded | uint32_t |
yes | Fairly weak but widely used for persisted hashes. |
CityHash64() |
base::span<const uint8_t> |
uint64_t |
yes (note 1) | Version 1.0.3. Has some known weaknesses. |
CityHash64WithSeed() |
base::span<const uint8_t> |
uint64_t |
yes (note 1) | Version 1.0.3. Has some known weaknesses. |
Cryptographic
There are no hashes in //base that provide cryptographic security.
| name | input | output | unchanging forever | notes |
|---|---|---|---|---|
MD5String() |
std::string |
std::string |
yes | INSECURE |
SHA1HashString |
std::string |
std::string |
yes | INSECURE |
Deprecated
Note: CRC32, Murmur2, and Murmur3 will be listed here.
Note 1: While CityHash is not guaranteed unchanging forever, the version used in Chrome is pinned to version 1.0.3.
