![]() ![]() We recommend password managers as a secure long term storage of keys. One extremely important aspect of symmetric encryption is that there is absolutely no way to decrypt the file if the key is lost. This is a central aspect when assessing if an encryption is good enough. In research, when you have an IRB - which you should always have if you collect information on individuals - no-one but the people listed in the IRB should have access to the key. Decryption also takes two inputs, the exact same key used when encrypting and the encrypted unreadable version of the information, and the output is the original readable version of the information.Īnyone with access to both the encrypted file and the key can decrypt and read the information, so when third party services encrypt our data it is never secure enough if someone else than you and your team have access to the key. Sharing a file in syncing services like DropBox is an example of that.Įncrypting using symmetric encryption takes two inputs, the encryption key and the information to be encrypted, and the output is the encrypted unreadable version of the information. This encryption is best suited for when you share a file both ways, meaning that both the sender and the receiver have equal access to the file. Advanced encryption may use such long passwords as key that the key becomes a file. “ Key” in this context is almost synonymous with password, but passwords are only one type of key. In symmetric encryption you both encrypt and decrypt information using the same key. All services recommended on this page are known to have up to date implementation of encryption algorithms. However, if you are using well-established services for which warnings are not found after a quick google search, then you should be fine. So even if a service provide, for example, symmetric encryption, it is possible that it is implemented with an outdated algorithm that is not secure. A typical researcher does not know the details on how they differ, but what a researcher should know is that some of these algorithms are outdated and can easily be hacked. One-way hashing - No password is used when encrypting, and there is no way decrypt anything that was one-way hashedįor each of the three types of encryption there are multiple algorithms that can be used to implement them.Asymmetric Encryption - Information can both be encrypted and decrypted but different passwords/keys are used when encrypting and decrypting.Symmetric Encryption - Information can both be encrypted and decrypted and the same password/key is used when encrypting and decrypting.The difference between these three encryption types are under which circumstances the information can be decrypted and what key or password is needed to do so. There are three types of encryption useful to understand to safely operate in the digital world and to safely handle PII data. Encryption keys that can decrypt sensitive data must be shared using password managers.When transferring or sharing sensitive data, the data both need to be encrypted-in-transit and encrypted-at-rest.They are symmetric encryption, asymmetric encryption and hashing. There are three main types of encryption algorithms relevant to our field.2.3.1 Example of use-case of one-way hashing.2.2.1 Use case - sending data from the field.2.1.1 Symmetric encryption software - VeraCrypt.
