README

        
Some WIP code to deal with img4 files in a decent manner.

Prereq: either libcompression or liblzfse; or build one in-tree (has precedence)

    git submodule init && git submodule update && make -C lzfse [CC="cross-cc"] [LD="cross-ld"]

Build:

    make [CC="cross-cc"] [LD="cross-ld"] [CORECRYPTO=1] [COMMONCRYPTO=1]

        COMMONCRYPTO=1	use Apple CommonCrypto instead of OpenSSL (Darwin-only)

        CORECRYPTO=1	use the included corecrypto sources (has precedence)

Examples:

./img4 \

    -i DeviceTree.n51ap.im4p \

    -o dtre.img4 \

    -M manifest.im4m \

    -N 0x1122334455667788 \

    -T rdtr

./img4 \

    -i kc_iPhone6,1_9.0_13A344.im4p \

    -o krnl.img4 \

    -k a6ff60f2fcf3cdcaaf735e1683418ff56828540cd92ac15f3144ed4dc9d5bcb34c01cc8154bc22c3658d82b6c439340b \

    -M manifest.im4m \

    -N 0x1122334455667788 \

    -P kc_iPhone6,1_9.0_13A344.bpatch \
