generate and verify the MAC. The default type is *MD5*, which is always
supported.
If *chronyd* was built with enabled support for hashing using a crypto library
-(nettle, nss, or libtomcrypt), the following functions are available: *MD5*,
+(Nettle, GnuTLS, NSS, or LibTomCrypt), the following functions are available: *MD5*,
*SHA1*, *SHA256*, *SHA384*, *SHA512*. Depending on which library and version is
*chronyd* using, some of the following hash functions and ciphers may
also be available:
to enable optional features:
* pkg-config: detection of development libraries
-* Nettle, NSS, or LibTomCrypt: secure hash functions (`SECHASH`)
+* Nettle, GnuTLS, NSS, or LibTomCrypt: secure hash functions (`SECHASH`)
* libcap: dropping root privileges on Linux (`DROPROOT`)
* libseccomp: system call filter on Linux (`SCFILTER`)
* GnuTLS and Nettle: Network Time Security (`NTS`)
