dd_rescue is a generic data copy and transformation tool. It copies data that's only partially readable or overwrites data with random numbers (data protection). It calculates secure hashes via a plugin. Plugins also allow to transform data -- compression and upcoming encryption are supported. The encryption plugin does exclusively support AES (in CTR, CBC or ECB mode) and is highly optimized, using the CPU support on x86 and armv8. The compression plugin uses liblzo.
See my [old page](http://www.garloff.de/kurt/linux/ddrescue/) for more information for now.
Binaries (debian and RPM packages) are available from the Open Build Service: https://download.opensuse.org/repositories/home:/garloff:/storage/

I always use dd_rescue instead of ddrescue. dd_rescue can handle being given the same input and output file and can do things like refresh magnetic recording. Additionally, it has encryption and compression functions.Reply from dd_rescuePosted 2022-11-05
Hi Tommyv6, I'm really glad the tool was useful to you! There are (and have been for many years) binary packages (.deb and .rpm) for various distributions for this tool built by the Open Build Service (one of the really nice tools out of the openSUSE community). I have added a link to the project description to make it more easily findable. -- Kurt
