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.
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
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". [1]
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.
