[dependabot[bot]]

Bumps secp256k1 from 0.17.2 to 0.22.2.

Changelog

Sourced from secp256k1's changelog.

0.22.2 - 2022-12-05

• Backport fix soundness issue with preallocated_gen_new

0.22.1 - 2022-03-10

• Reintroduce accidentally removed possibility to create SharedSecret from byte serialization

0.22.0 - 2022-03-08

• Disable bitcoin_hashes/std by default; add bitcoin-hashes-std feature to re-enable it
• Rename more schnorrsig methods to schnorr
• Obfuscate SharedSecret string serialization
• Simplify SharedSecret API to use a 32-byte buffer; users of custom hashes should now use bare arrays rather than this type.
• Change serde serialization of Parity from i32 to u8; clean up error handling

0.21.3 - 2022-01-31

• Several documentation improvements (#366, #365, #373, #381, #369, #389, #391, #397, #399, #340)
• Deprecate the generate_schnorrsig_keypair method (unclear value)
• Add serde traits to KeyPair
• Redo the API of the new Parity type to more clearly match our desired semantics; the From<i32> impl on this type is now deprecated. Also #400.
• Randomize the global context on creation when possible; weaken global-context-less-secure feature accordingly.
• Improve the global context API
• Fix the Debug impl for RecoverableSignature
• Implement LowerHex and Display

0.21.0 - 2022-01-02

• Fix KeyPair::from_seckey_slice error return value
• Reduce the lowmemory precomp table size
• Add KeyPair::serialize_sec
• Increase bitcoin_hashes version to 0.10; rename secp256k1::bitcoin_hashes module to secp256k1::hashes to align with bitcoin crate naming
• Add new error variant for PublicKey::combine_keys
• Change Display and Debug for secret keys to only output a truncated hash
• Improve documentation
• Implement Hash for schnorrsig::Signature
• Refactor modules to put Schnorr and ECDSA on more equal footing
• Add serde traits for KeyPair type
• Fix context bound requirements for a few methods
• Add a static immutable-zero aligned type
• Change tweak_add_assign and tweak_add_check to use an opaque Parity type rather than a boolean

0.20.3 - 2021-06-10

• Fix SecretKey validation in from_str
• Add global-context-less-secure feature which creates a non-randomized global context (and does not require rand or std)
• Add schnorrsig::KeyPair::from_secret_key convenience function
• Add combine_keys function to PublicKey
• Reduce symbol visibility in C compilation to allow LTO to work
