New [`nix hash convert`](https://github.com/NixOS/nix/issues/8876) sub command with a fast track
|
|
to stabilization! Examples:
|
|
|
|
- Convert the hash to `nix32`.
|
|
|
|
```bash
|
|
$ nix hash convert --algo "sha1" --to nix32 "800d59cfcd3c05e900cb4e214be48f6b886a08df"
|
|

|
|
```
|
|
`nix32` is a base32 encoding with a nix-specific character set.
|
|
Explicitly specify the hashing algorithm (optional with SRI hashes) but detect hash format by the length of the input
|
|
hash.
|
|
- Convert the hash to the `sri` format that includes an algorithm specification:
|
|
```bash
|
|
nix hash convert --algo "sha1" "800d59cfcd3c05e900cb4e214be48f6b886a08df"
|
|
sha1-gA1Zz808BekAy04hS+SPa4hqCN8=
|
|
```
|
|
or with an explicit `-to` format:
|
|
```bash
|
|
nix hash convert --algo "sha1" --to sri "800d59cfcd3c05e900cb4e214be48f6b886a08df"
|
|
sha1-gA1Zz808BekAy04hS+SPa4hqCN8=
|
|
```
|
|
- Assert the input format of the hash:
|
|
```bash
|
|
nix hash convert --algo "sha256" --from nix32 "ungWv48Bz+pBQUDeXa4iI7ADYaOWF3qctBD/YfIAFa0="
|
|
error: input hash 'ungWv48Bz+pBQUDeXa4iI7ADYaOWF3qctBD/YfIAFa0=' does not have the expected format '--from nix32'
|
|
nix hash convert --algo "sha256" --from nix32 "1b8m03r63zqhnjf7l5wnldhh7c134ap5vpj0850ymkq1iyzicy5s"
|
|
sha256-ungWv48Bz+pBQUDeXa4iI7ADYaOWF3qctBD/YfIAFa0=
|
|
```
|
|
|
|
The `--to`/`--from`/`--algo` parameters have context-sensitive auto-completion.

- `nix hash to-base32 $hash1 $hash2`: Use `nix hash convert --to nix32 $hash1 $hash2` instead.
|
|
- `nix hash to-base64 $hash1 $hash2`: Use `nix hash convert --to base64 $hash1 $hash2` instead.
|
|
- `nix hash to-sri $hash1 $hash2`: : Use `nix hash convert --to sri $hash1 $hash2`
|
|
or even just `nix hash convert $hash1 $hash2` instead.
