Michal Kucharczyk	a756baf3b2	Support for keyring in runtimes (#2044) ... This functionality is required for #1984. This PR enables [`sp-keyring`](https://github.com/paritytech/polkadot-sdk/blob/21d36b7b4229c4d5225944f197918cde23fda4ea/substrate/primitives/keyring/src/sr25519.rs#L31-L40) in `no-std` environments, allowing to generate the public key (e.g. `AccountKeyring::Alice.public().to_ss58check()`), which can be later used in the any of built-in [_runtime-genesis-config_ variant](https://github.com/paritytech/polkadot-sdk/blob/21d36b7b4229c4d5225944f197918cde23fda4ea/polkadot/node/service/src/chain_spec.rs#L1066-L1073). The proposal is as follows: - expose [`core::Pair` trait](https://github.com/paritytech/polkadot-sdk/blob/d6f15306282e3de848a09c9aa9cba6f95a7811f0/substrate/primitives/core/src/crypto.rs#L832) in `no-std`, - `full_crypto` feature enables `sign` method, - `std` feature enables `generate_with_phrase` and `generate` methods (randomness is required), - All other functionality, currently gated by `full_crypto` will be available unconditionally (`no-std`): -- `from_string` -- `from_string_with_seed` -- `from seed` -- `from_seed_slice` -- `from_phrase` -- `derive` -- `verify` --- Depends on https://github.com/rust-bitcoin/rust-bip39/pull/57 --------- Co-authored-by: command-bot <> Co-authored-by: Davide Galassi <davxy@datawok.net>	2024-03-12 11:43:31 +00:00
Michal Kucharczyk	f6548aee31	keyring: remove lazy_static public keys hash maps (#2387) ... The `lazy_static` package does not work well in `no-std`: it requires `spin_no_std` feature, which also will propagate into `std` if enabled. This is not what we want. This PR removes public/private key hash-maps and replaces them with simple static byte arrays. `&T` versions of `AsRef/Deref/From` traits implementation were removed. Little const helper for converting hex strings into array during compile time was also added. (somewhat similar to _hex_literal_). --------- Co-authored-by: command-bot <> Co-authored-by: Koute <koute@users.noreply.github.com>	2023-12-11 15:21:20 +01:00
