FINALLY!!! After 3 years searching/waiting I was able to find this unicorn and look at some its innerworkings! :phew: I confirmed the suspicions that the LeCroy WS3000 FW packages are AES128-CBC encrypted and the licensing methods used are the same as all other old WinCE LeCroy stuff. However it uses a different Blowfish key from the one that is public. The analysis is ongoing as I want also to try and correctly parse the Siglent SDS3000 FW packages. :popcorn: As a useless teaser, here is the "usual" options config file taken from inside. |

Siglent SDS3000 FW packages use a different AES128-CBC key but the options licenses' Blowfish key is the same as in LeCroy WS3000. Here is a more complete parsing of the SDS3000X_8.7.0.6.fla FW package: --- Code: ---00000000 - Manufacturer: Shglent 00000010 - Name 2: RELSVR (Release Version) 00000016 - FW Version: 8_7 00000020 - Encrypted Block [00000020-0B86089F] Size: 0B860880 00000020 - Block Type: 00000101 - nk.nb0 00000024 - Block Size: 0B860870 SIZE OK 0B8608A0 - Checksum: EAD7413C CKSUM OK 0B8608A4 - Manufacturer: Shglent 0B8608B4 - Name 2: RELSVR (Release Version) 0B8608BA - FW Version: 8_7 0B8608C4 - Encrypted Block [0B8608C4-0BA22913] Size: 001C2050 0B8608C4 - Block Type: 00000104 - LeCroyLG.bmp 0B8608C8 - Block Size: 001C2040 SIZE OK 0BA22914 - Checksum: 0047D675 CKSUM OK 0BA22918 - Manufacturer: Shglent 0BA22928 - Name 2: RELSVR (Release Version) 0BA2292E - FW Version: 8_7 0BA22938 - Encrypted Block [0BA22938-0BB8CFC7] Size: 0016A690 0BA22938 - Block Type: 00000105 - LcdFpga.bin 0BA2293C - Block Size: 0016A680 SIZE OK 0BB8CFC8 - Checksum: 0166690E CKSUM OK 0BB8CFCC - Manufacturer: Shglent 0BB8CFDC - Name 2: RELSVR (Release Version) 0BB8CFE2 - FW Version: 8_7 0BB8CFEC - Encrypted Block [0BB8CFEC-0BBCCFFB] Size: 00040010 0BB8CFEC - Block Type: 00000103 - LeCroyEN.up 0BB8CFF0 - Block Size: 00040000 SIZE OK 0BBCCFFC - Checksum: 00AD74D7 CKSUM OK 0BBCD000 - Manufacturer: Shglent 0BBCD010 - Name 2: RELSVR (Release Version) 0BBCD016 - FW Version: 8_7 0BBCD020 - Encrypted Block [0BBCD020-0BBD146F] Size: 00004450 0BBCD020 - Block Type: 00000106 - ??? 0BBCD024 - Block Size: 00004440 SIZE OK 0BBD1470 - Checksum: 001A4498 CKSUM OK 0BBD1474 - Manufacturer: Shglent 0BBD1484 - Name 2: RELSVR (Release Version) 0BBD148A - FW Version: 8_7 0BBD1494 - Encrypted Block [0BBD1494-0BCA47E3] Size: 000D3350 0BBD1494 - Block Type: 00000107 - Registry ???
