This skill provides multi-algorithm cryptography support (ED25519, P-256, RSA-4096), symmetric encryption (AES, ChaCha20), and BIP39/44 HD wallet derivation. All operations return CryptoResult<T> for explicit error handling—no exceptions for crypto failures.
High-intent search queries and answers about installing and using this skill.
Signing and verification across ED25519, P-256, and RSA-4096 algorithms use deterministic hashing through a unified interface. Generate a key set, hash your message, then call the sign and verify methods—all operations return CryptoResult<T> for explicit success or failure handling without exceptions.
This skill supports AES and ChaCha20 for symmetric encryption and decryption operations. Both algorithms encrypt data through the unified cryptographic interface and return CryptoResult<T>, making them suitable for secure message workflows within Sorcha.
Yes. BIP39/44 HD wallet derivation is built in for generating and deriving wallet keys. Provide the necessary inputs and the skill returns derived keys via CryptoResult<T>, enabling wallet key management and transaction authorization tasks.
All operations return CryptoResult<T> for explicit error signaling—no exceptions are thrown for crypto failures. This design lets you handle success and failure cases directly in your application logic.
Yes. The skill's signing, verification, and HD wallet derivation features are applicable to transaction authorization and wallet key management workflows, making it suitable for blockchain and payment transaction tasks.
Cryptographic primitives must be provided by Sorcha libraries. The skill exposes signing, verification, encryption, and HD-wallet derivation operations that depend on these Sorcha-supplied primitives to function.
