使用方式

通过命令行使用，需要提供加密的IPA文件、输出路径和凭证文件。

查看 README 依据

python -m pip install -r requirements.txt make ``` On macOS, `make` also builds the credential-retrieval bundle and requires Xcode and `ldid`. On Linux, it builds the decryptor. ## Decrypt ```sh python decrypt.py /path/to/encrypted.ipa /path/to/decrypted.ipa \ --credential /path/to/credential.bin ``` If `--credential` is omitted, the tool reads `./credential.bin`. The output path must not exist. The decryptor uses each IPA's SINF and SUPF records to derive page keys, decrypt its encrypted arm64 pages, and clear `cryptid`.

部署要求

需要 Python 3.10+、C编译器，macOS上构建还需Xcode和ldid。

# IPA decryptor Decrypt FairPlay-encrypted apps using a 16-byte credential for the account that owns each IPA. [Credential retrieval](credential-retrieval/README.md) gets it from a supported jailbroken device and writes `credential.bin` to the chosen output directory. Decryption runs on macOS and Linux. Supports version-3 and version-5 SUPF, 448-byte and 440-byte SINF `priv` records, and encrypted arm64 Mach-O slices. A 440-byte record must end in eight zero bytes. ## Set up From this directory, with Python 3.10+ and a C compiler: ```sh python3 -m venv .venv . .venv/bin/activate

python -m pip install -r requirements.txt make ``` On macOS, `make` also builds the credential-retrieval bundle and requires Xcode and `ldid`. On Linux, it builds the decryptor. ## Decrypt ```sh python decrypt.py /path/to/encrypted.ipa /path/to/decrypted.ipa \ --credential /path/to/credential.bin ``` If `--credential` is omitted, the tool reads `./credential.bin`. The output path must not exist. The decryptor uses each IPA's SINF and SUPF records to derive page keys, decrypt its encrypted arm64 pages, and clear `cryptid`.
