	      Warning
	      This  program  is	 experimental <../../development/experimental-
	      features.md#xp-feature-nix-command> and its interface is subject
	      to change.

Name
       nix hash	convert	- convert between hash formats

Synopsis
       nix hash	convert	[option...] hashes...

Examples
       •  Convert a hash to nix32 (a  base-32  encoding	 with  a  Nix-specific
	  character set).

       $ nix hash convert --hash-algo sha1 --to	nix32 800d59cfcd3c05e900cb4e214be48f6b886a08df
       vw46m23bizj4n8afrc0fj19wrp7mj3c0

       •  Convert  a hash to the sri format <https://developer.mozilla.org/en-
	  US/docs/Web/Security/Subresource_Integrity> that includes  an	 algo-
	  rithm	specification:

       # nix hash convert --hash-algo sha1 800d59cfcd3c05e900cb4e214be48f6b886a08df
       sha1-gA1Zz808BekAy04hS+SPa4hqCN8=

	      or with an explicit --to format:

       # nix hash convert --hash-algo sha1 --to	sri 800d59cfcd3c05e900cb4e214be48f6b886a08df
       sha1-gA1Zz808BekAy04hS+SPa4hqCN8=

       •  Assert the input format of the hash:

       # nix hash convert --hash-algo sha256 --from nix32 ungWv48Bz+pBQUDeXa4iI7ADYaOWF3qctBD/YfIAFa0=
       error: input hash 'ungWv48Bz+pBQUDeXa4iI7ADYaOWF3qctBD/YfIAFa0='	does not have the expected format '--from nix32'

       # nix hash convert --hash-algo sha256 --from nix32 1b8m03r63zqhnjf7l5wnldhh7c134ap5vpj0850ymkq1iyzicy5s
       sha256-ungWv48Bz+pBQUDeXa4iI7ADYaOWF3qctBD/YfIAFa0=
