Data encryption

Q: What is the difference between symmetric and asymmetric encryption?

Symmetric encryption uses one shared key. Asymmetric encryption uses a pair of public and private keys.

Data encryption uses a key to turn readable data into unreadable ciphertext, so that only authorized parties with the matching key can read it again.

What is data encryption?

Data encryption uses a key to turn readable data into unreadable ciphertext. Only someone with the matching key can decrypt and read it. It is a core tool of cryptography and the basis for data protection and data security.

Encryption in transit and at rest

A distinction is made between encryption in transit and at rest. In transit, the TLS protocol (Transport Layer Security) secures the connection, for example when loading a website or uploading a file. At rest, stored data on the server is encrypted. Comprehensive protection covers both states.

Symmetric and asymmetric encryption

Symmetric encryption uses the same key on both sides. The most common standard is AES-256, considered practically unbreakable by today's standards and used mainly to protect data at rest. Asymmetric encryption uses a key pair of public and private keys, mainly for secure key exchange and digital signatures. Modern systems combine both.

How SecureCloud encrypts data

SecureCloud encrypts data in transit (TLS) and at rest with AES-256. Combined with granular access rights and hosting in Germany, this reliably protects company data.
