Particular data binary large objects can be encrypted in a way that salt is added and/or an external user-prompted password (aka "Strong Key Protection") is required. The use of a salt is a per-implementation option – i.e. under the control of the application developer – and is not controllable by the end user or system administrator.
This section shows file formats for encrypted general data, rather than a specific program's data. AXX – Encrypted file, created with AxCrypt; EEA – An encrypted CAB, ostensibly for protecting email attachments; TC – Virtual encrypted disk container, created by TrueCrypt; KODE – Encrypted file, created with KodeFile
Transparent Data Encryption (often abbreviated to TDE) is a technology employed by Microsoft, IBM and Oracle to encrypt database files. TDE offers encryption at file level. TDE enables the encryption of data at rest, encrypting databases both on the hard drive and consequently on backup media. It does not protect data in transit nor data in use.
Crypto-shredding or crypto erase (cryptographic erasure) is the practice of rendering encrypted data unusable by deliberately deleting or overwriting the encryption keys: assuming the key is not later recovered and the encryption is not broken, the data should become irrecoverable, effectively permanently deleted or "shredded".

Encryption in transit protects data as it is being transmitted to and from the cloud service. [20] Encryption at rest protects data that is stored at the service provider. Encrypting data in an on-premises cloud service on-ramp system can provide both kinds of encryption protection. There are several options available to avoid security issues.
The Encrypting File System (EFS) on Microsoft Windows is a feature introduced in version 3.0 of NTFS [1] that provides filesystem-level encryption.The technology enables files to be transparently encrypted to protect confidential data from attackers with physical access to the computer.
Crypt is commonly [11] used to encrypt / decrypt media, for streaming, on consumer storage services such as Google Drive. Rclone's configuration file contains the crypt password. The password can be lightly obfuscated, or the whole rclone.conf file can be encrypted. [39] Crypt can either encrypt file content and name, or additionally full paths.
