ipcrypt2

D bindings for IPCrypt2, a simple and secure IP address obfuscation scheme.

IPCrypt2 is a format-preserving encryption scheme for IPv4 and IPv6 addresses. It allows IP addresses to be encrypted while maintaining their format, making it suitable for logging and data retention purposes where IP addresses need to be pseudonymized.

Features

Format-preserving encryption for both IPv4 and IPv6 addresses
Cryptographically secure using AES-128 as the underlying cipher
Preserves subnets: addresses sharing a prefix are encrypted to addresses sharing the same prefix
Deterministic: same input and key always produces the same output
Fast and constant-time operation

Functions

ip16ToSockaddr sockaddr_storage ip16ToSockaddr(const(ubyte)[] ip16): Converts a 16-byte IP address to a sockaddr_storage.
ip16ToStr string ip16ToStr(const(ubyte)[] ip16): Converts a 16-byte IP address to a string.
ipStrToIP16 ubyte[IPCRYPT_KEYBYTES] ipStrToIP16(string ipStr): Converts an IP address string to a 16-byte representation.
sockaddrToIP16 ubyte[IPCRYPT_KEYBYTES] sockaddrToIP16(sockaddr* sa): Converts a sockaddr to a 16-byte IP address.

Structs

IPCrypt2 struct IPCrypt2: IPCrypt context, providing encryption/decryption of IP addresses. Ensures proper initialization and cleanup of the underlying IPCrypt context.
IPCryptNDXCtx struct IPCryptNDXCtx: IPCryptNDX context, providing extended encryption/decryption. Ensures proper initialization and cleanup of the underlying IPCryptNDX context.
