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 that includes an algorithm 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=
