Function create_key 

pub fn create_key(
    password: &str,
    user_ids: &[&str],
    cipher: CipherSuite,
    creation_time: Option<DateTime<Utc>>,
    expiration_time: Option<DateTime<Utc>>,
    subkeys_expiration: Option<DateTime<Utc>>,
    which_keys: SubkeyFlags,
    can_primary_sign: bool,
    can_primary_expire: bool,
) -> Result<GeneratedKey>

Generate a new OpenPGP key pair.

Arguments

• password - Password to protect the secret key
• user_ids - List of user IDs (e.g., “Name email@example.com”)
• cipher - Cipher suite to use (see CipherSuite for options)
• creation_time - Optional creation time (defaults to now)
• expiration_time - Optional expiration time for the primary key
• subkeys_expiration - Optional expiration time for subkeys
• which_keys - Which subkeys to generate (see SubkeyFlags)
• can_primary_sign - Whether the primary key can sign
• can_primary_expire - Whether the primary key can expire

Returns

The generated key with public key (armored), secret key (binary), and fingerprint.

Example

Generate a Curve25519 key (fast):

use wecanencrypt::{create_key, CipherSuite, SubkeyFlags};

let key = create_key(
    "my_password",
    &["Alice <alice@example.com>"],
    CipherSuite::Cv25519,
    None, None, None,
    SubkeyFlags::all(),
    false,
    true,
).unwrap();

println!("Fingerprint: {}", key.fingerprint);
println!("Public key:\n{}", key.public_key);

Generate an RSA-4096 key (slow, ~10s in release mode):

// Ignored: RSA-4096 key generation is slow (~10s release, ~600s debug)
use wecanencrypt::{create_key, CipherSuite, SubkeyFlags};

let key = create_key(
    "my_password",
    &["Bob <bob@example.com>"],
    CipherSuite::Rsa4k,
    None, None, None,
    SubkeyFlags::all(),
    false,
    true,
).unwrap();
