Function hash_algorithm 

pub const fn hash_algorithm() -> &'static str

Returns the name of the active hash algorithm

The algorithm is selected at compile time based on feature flags:

• fast — GxHash (requires AES-NI), falls back to AHash
• secure — AHash (DoS-resistant)
• crypto — Blake3 (cryptographic)
• default — DefaultHasher (std) or FNV-1a (no_std)

Examples

let algo = domain_key::hash_algorithm();
println!("Using hash algorithm: {algo}");
