![]() All cryptographic metadata is stored in the headers of files, so encrypted data can be easily moved, stored for backup and recovered. That includes, for example, a user's entire home directory or single dedicated directories within it. Instead, you can mount eCryptfs on top of any single directory to protect it. ![]() One distinguished feature is that the encryption is stacked on an existing filesystem eCryptfs can be mounted onto any single existing directory and does not require a separate partition (or size pre-allocation).Īs mentioned in the summary eCryptfs does not require special on-disk storage allocation effort, such as a separate partition or pre-allocated space. For comparison of the two you can refer to Data-at-rest encryption#Block device vs stacked filesystem encryption. In implementation eCryptfs differs from dm-crypt, which provides a block device encryption layer, while eCryptfs is an actual file-system – a stacked cryptographic file system. ![]() It guides you through the process of creating a private and secure encrypted directory within your home directory to store sensitive files and private data. This article describes basic usage of eCryptfs. ![]()
