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
sriformat that includes an algorithm specification:# nix hash convert --hash-algo sha1 800d59cfcd3c05e900cb4e214be48f6b886a08df sha1-gA1Zz808BekAy04hS+SPa4hqCN8=or with an explicit
--toformat:# 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
nix hash convert converts hashes from one encoding to another.
Options
- 
--fromhash-formatHash format (
base16,nix32,base64,sri). - 
--hash-algohash-algoHash algorithm (
md5,sha1,sha256, orsha512). Can be omitted for SRI hashes. - 
--tohash-formatHash format (
base16,nix32,base64,sri). Default:sri. 
Logging-related options
- 
Set the logging verbosity level to 'debug'.
 - 
--log-formatformatSet the format of log output; one of
raw,internal-json,barorbar-with-logs. - 
--print-build-logs/-LPrint full build logs on standard error.
 - 
Decrease the logging verbosity level.
 - 
--verbose/-vIncrease the logging verbosity level.
 
Miscellaneous global options
- 
Show usage information.
 - 
Disable substituters and consider all previously downloaded files up-to-date.
 - 
--optionname valueSet the Nix configuration setting name to value (overriding
nix.conf). - 
Consider all previously downloaded files out-of-date.
