AES-encryption tool with loop-AES support
aespipe is an encryption tool that reads from standard input and writes to standard output. It uses the AES (Rijndael) cipher. . aespipe can be used for non-destructive in-place encryption of existing disk partitions for use with the loop-AES encrypted loopback kernel module. . It can also be used as an encryption filter to create and restore encrypted tar/cpio backup archives and to read/write and convert loop-AES compatible encrypted images. . Note that aespipe does not store any length information with the encrypted images, so it cannot be used as general purpose filter for encryption, but only for certain formats like tar.
