To use it, the appropriate kernel configuration parameters need to be set: Device Drivers ---> [*] Multiple devices driver support (RAID and LVM) ---> [CONFIG_MD] <*/M> Device mapper support [CONFIG_BLK_DEV_DM] <*/M> Crypt target support [CONFIG_DM_CRYPT] Cryptographic API ---> <*/M> XTS support [CONFIG_CRYPTO_XTS] <*/M> SHA224 and SHA256 digest algorithm [CONFIG_CRYPTO_SHA256] <*/M> AES cipher algorithms [CONFIG_CRYPTO_AES] <*/M> User-space interface for symmetric key cipher algorithms [CONFIG_CRYPTO_USER_API_SKCIPHER] For tests: <*/M> Twofish cipher algorithm [CONFIG_CRYPTO_TWOFISH] cryptsetup Install cryptsetup by running the following commands: ./configure --prefix=/usr && make To test the result, issue as the root user: make check. Some tests will fail if appropriate kernel configuration options are not set. Some additional options that may be needed for tests are: CONFIG_SCSI_LOWLEVEL, CONFIG_SCSI_DEBUG, CONFIG_BLK_DEV_DM_BUILTIN, CONFIG_CRYPTO_USER, CONFIG_CRYPTO_CRYPTD, CONFIG_CRYPTO_LRW, CONFIG_CRYPTO_XTS, CONFIG_CRYPTO_ESSIV, CONFIG_CRYPTO_CRCT10DIF, CONFIG_CRYPTO_AES_TI, CONFIG_CRYPTO_AES_NI_INTEL, CONFIG_CRYPTO_BLOWFISH, CONFIG_CRYPTO_CAST5, CONFIG_CRYPTO_SERPENT, CONFIG_CRYPTO_SERPENT_SSE2_X86_64, CONFIG_CRYPTO_SERPENT_AVX_X86_64, CONFIG_CRYPTO_SERPENT_AVX2_X86_64, and CONFIG_CRYPTO_TWOFISH_X86_64. Now, as the root user: make install Because of the number of possible configurations, setup of encrypted volumes is beyond the scope of the BLFS book. Please see the configuration guide in the cryptsetup FAQ.
