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=' has format 'base64', but '--from nix32' was specified
   
  # nix hash convert --hash-algo sha256 --from nix32 1b8m03r63zqhnjf7l5wnldhh7c134ap5vpj0850ymkq1iyzicy5s
  sha256-ungWv48Bz+pBQUDeXa4iI7ADYaOWF3qctBD/YfIAFa0=
