This message appears to be encoded using hexadecimal:
Ox 57 65 20 6E 65 65 64 20 74 6F 20 6D 65 65 74 2C 20 74 68 65 20 70 6F 6C 69 63 65 20 61 72 65 20 62 65 63 6F 6D 69 6E 67 20 73 75 73 70 69 63 69 6F 75 73
The next message appears to be base64:

The FBI are stumped, a double cipher was used to encode a message. It looks like hexadecimal, but the ASCII text does not look like English. They also found the passphrase: secret. The message appears to be a sort of polyalphabetic substitution.
Determine what cipher is considered a polyalphabetic substitution cipher:
Ox 4C 6C 67 20 72 78 6D 73 67 6D 20 6E 6D 65 64 20 78 63 62 69 20 69 64 65 65 76 20 73 67 20 58 76 6B 75 65 72 20 45 65 61 20 39 6B 6C 20 78 70 65 65 6B 70 72 20 73 78 20 31 30 63 64 2E 20 43 68 6D 20 61 6B 63 70 20 6D 73 6F 67 20 6B 6C 78 61 76 20 67 64 65 62 64 20 77 61 6A 78 78 65 20 68 71 6E 72 2C 20 70 7A 6D 6E 76 20 4D 20 62 66 6E 67 74 78 20 6D 7A 69 20 75 70 77 6D 77 71 20 79 7A 78 61 20 73 20 67 71 75 69 20 6D 7A 65 76 20 6E 6D 65 64 20 76 67 69 73 6E 6C 69 20 76 79 69 20 6C 7A 6D 72 64 69 67 6C 2E
