* uencrypt: split common and library-specific codeEneas U de Queiroz2023-03-175-293/+379
| | | | | | | | | | | | | | This splits the code in 4 files: - uencrypt.h - uencrypt.c - main program - uencrypt-openssl.c - OpenSSL/wolfSSL implementation - uencrypt-mbedtls - mbedTLS implementation Other changes, accounting for ~400 bytes increase in ipk size: - more error condition checking and reporting, - hide key and iv command line arguments Signed-off-by: Eneas U de Queiroz <cotequeiroz@gmail.com>
* uencrypt: add support for mbedtlsEneas U de Queiroz2023-03-173-26/+258
| | | | | | | | | | | | | | This commit includes some additional changes: - better handling of iv and keys in openssl/wolfssl variants - fix compiler warnings and whitespace - build all 3 variants as separate packages - adjust the new package name in targets' DEVICE_PACKAGES - remove PKG_FLAGS:=nonshared [Beeline SmartBox Flash - OK] Tested-by: Mikhail Zhilkin <csharper2005@gmail.com> [after test: replaced a hardcoded IV size of 16 by cipher_info->iv_size] Signed-off-by: Eneas U de Queiroz <cotequeiroz@gmail.com>
* uencrypt: support all available ciphersNick French2022-08-191-11/+44
| | | | | | | | | | | | | Modify uencrypt to support any cipher provided by ssl library. Original tool supported only AES-128-CBC to decrypt the config mtd of Arcadyan WG430223/WG443223. TP-Link Deco S4 has mtd configuration encrypted with DES-ECB, so make the cipher generic to support both routers.

* uencrypt: add package to decrypt WG4хх223 configEneas U de Queiroz2022-07-192-0/+137
This adds a simple AES-128-CBC encryption/decryption program using either wolfSSL or OpenSSL as backend to decrypt Arcadyan WG4xx223 configuration partitions. The ipk size is 3,355 bytes. Signed-off-by: Eneas U de Queiroz <cotequeiroz@gmail.com>
