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

|
• |
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

Hash algorithm (md5, sha1, sha256, or sha512). Can be omitted for SRI hashes.
|
• |
--to hash-format |
Hash format (base16, nix32, base64, sri). Default: sri.
