Der chinesische Coder hrimfaxi hat heute einen PSARDumper für die kürzlich erschienene Firmware 6.30 released. Laut hrimfaxi hat Sony in der 6.30 zwei neue PRX-Typen genutzt. Hier das Original-Posting von dem Coder:

In 6.30 firmware Sony has add two new types of PRX to protect their executable. But we only spend one day to crack that.
Currently there is only psp phat key, but it should be enough though.

Key detail:
/* 6.30 phat kernel s_code 0×43 type 3 */
u8 key_4c9484f0[16] = {
0×36, 0xB0, 0xDC, 0xFC, 0×59, 0x2A, 0×95, 0x1D,
0×80, 0x2D, 0×80, 0x3F, 0xCD, 0×30, 0xA0, 0x1B,
};

/* 6.30 phat kernel-2, s_code 0x5b type 3 */
u8 key_457b80f0[16] = {
0xd4, 0×35, 0×18, 0×02, 0×29, 0×68, 0xfb, 0xa0,
0x6a, 0xa9, 0xa5, 0xed, 0×78, 0xfd, 0x2e, 0x9d
};

/* used by vshmain.prx, s_code 0x5a, type 3 */
u8 key_380280f0[16] = {
0×97, 0×09, 0×12, 0xD3, 0xDB, 0×02, 0xBD, 0xD8,
0xE7, 0×74, 0×51, 0xFE, 0xF0, 0xEA, 0x6C, 0x5C,
};

DecryptPRX2 cannot handle these new “type 3″ prx, so I imported PSPCipher kprx_decrypt function to make this psardumper to work.

After decrypting, a new game key (0xd91680f0) is found in mesg_led_01.prx. It is likely we kicked sony’s a** again.

Credit: tpu dumped the IPL, and I found out what happened to the IPL decryptor.
