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 charac-
	ter set).

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

     *	Convert a hash to the sri format that includes an  algorithm  specifica-
	tion:

     # 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=

Description

     *	--hash-algo hash-algo

	Hash  algorithm  (blake3,  md5, sha1, sha256, or sha512). Can be omitted
	for SRI hashes.

     *	--to hash-format

	Hash format (base16, nix32, base64, sri). Default: sri.

   Logging-related options
     *	--debug

	Set the logging verbosity level to `debug'.

     *	--log-format format
