Head's up guys! Homebrew coder hrimfaxi has released a new version of PSARDumper to dump and decrypt the recently released PSP firmware 6.30.

Developer's note:

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 0x43 type 3 */
u8 key_4c9484f0[16] = {
0x36, 0xB0, 0xDC, 0xFC, 0x59, 0x2A, 0x95, 0x1D,
0x80, 0x2D, 0x80, 0x3F, 0xCD, 0x30, 0xA0, 0x1B,
};

/* 6.30 phat kernel-2, s_code 0x5b type 3 */
u8 key_457b80f0[16] = {
0xd4, 0x35, 0x18, 0x02, 0x29, 0x68, 0xfb, 0xa0,
0x6a, 0xa9, 0xa5, 0xed, 0x78, 0xfd, 0x2e, 0x9d
};

/* used by vshmain.prx, s_code 0x5a, type 3 */
u8 key_380280f0[16] = {
0x97, 0x09, 0x12, 0xD3, 0xDB, 0x02, 0xBD, 0xD8,
0xE7, 0x74, 0x51, 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 ass again.

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

Note: this source has been already covered by GPLv3 because of the usage of PSPCipher source.
