RMEx automatically encrypts key information relating to credit cards, bank information and a all social security numbers. When information is backed up, it is the encrypted data that gets saved. Complete backups (all data) can also be encrypted using different 3rd party products (there are hardware and software-based solutions).
We offer 128-bit encryption (which is very very strong). Key size can indicate how weak or strong the encryption is. As a general rule, the greater the key size, the better the data is protected (e.g., a 256-bit key generally provides better protection than a 128-bit key). However, this is not always true. For example, data encrypted with the RSA algorithm using a 256-bit key is not as safe as data encrypted using the AES algorithm using a 128-bit key.
