I managed to copy the Firmware out of a device and tried to extract to content with binwalk but the Signature tells it's encoded with OpenSSL
Which are the possible ways to find out which type of chipper has been used and so on. Cheers,

As mentioned in the comments, OpenSSL salted format (if that's indeed what you have) stores no information about the encryption used. You can probably guess some things, e.g. the block size from the size of the encrypted data, but to know for sure you need access to the code which processes the file (e.g. the firmware dumped from the device or the firmware updater if it does the decryption). Without access to that this question can't really be answered.
