In the question “What are the best file encryption tools?” dm-crypt via LUKS is … Entering the passphrase to decrypt the disk at boot can become quite tedious. Also, cryptsetup supports "detached header", where the header can be stored in a separate file. From "Figure 2: LUKS2 binary header on-disk structure" in LUKS2 On-Disk Format Specification, hdr_size is 8 bytes long and starts at byte 8 in the binary header.
