Struct ssh_key::private::PrivateKey

pub struct PrivateKey { /* private fields */ }

SSH private key.

Implementations

impl PrivateKey

pub fn new(key_data: KeypairData, comment: impl Into<String>) -> Result<Self>

This is supported on crate feature alloc only.

Create a new unencrypted private key with the given keypair data and comment.

On no_std platforms, use PrivateKey::from(key_data) instead.

pub fn from_openssh(input: impl AsRef<[u8]>) -> Result<Self>

Parse an OpenSSH-formatted PEM private key.

OpenSSH-formatted private keys begin with the following:

-----BEGIN OPENSSH PRIVATE KEY-----

pub fn from_bytes(bytes: &[u8]) -> Result<Self>

Parse a raw binary SSH private key.

pub fn encode_openssh<'o>(
    &self,
    line_ending: LineEnding,
    out: &'o mut [u8]
) -> Result<&'o str>

Encode OpenSSH-formatted (PEM) private key.

pub fn to_openssh(&self, line_ending: LineEnding) -> Result<Zeroizing<String>>

This is supported on crate feature alloc only.

Encode an OpenSSH-formatted PEM private key, allocating a self-zeroizing String for the result.

pub fn to_bytes(&self) -> Result<Zeroizing<Vec<u8>>>

This is supported on crate feature alloc only.

Serialize SSH private key as raw bytes.

pub fn read_openssh_file(path: &Path) -> Result<Self>

This is supported on crate feature std only.

Read private key from an OpenSSH-formatted PEM file.

pub fn write_openssh_file(
    &self,
    path: &Path,
    line_ending: LineEnding
) -> Result<()>

This is supported on crate feature std only.

Write private key as an OpenSSH-formatted PEM file.

pub fn decrypt(&self, password: impl AsRef<[u8]>) -> Result<Self>

This is supported on crate feature encryption only.

Attempt to decrypt an encrypted private key using the provided password to derive an encryption key.

Returns Error::Decrypted if the private key is already decrypted.

pub fn encrypt(
    &self,
    rng: impl CryptoRng + RngCore,
    password: impl AsRef<[u8]>
) -> Result<Self>

This is supported on crate feature encryption only.

Encrypt an unencrypted private key using the provided password to derive an encryption key.

Uses the following algorithms:

• Cipher: Cipher::Aes256Ctr
• KDF: Kdf::Bcrypt (i.e. bcrypt-pbkdf)

Returns Error::Encrypted if the private key is already encrypted.

pub fn encrypt_with(
    &self,
    cipher: Cipher,
    kdf: Kdf,
    checkint: u32,
    password: impl AsRef<[u8]>
) -> Result<Self>

This is supported on crate feature encryption only.

Encrypt an unencrypted private key using the provided cipher and KDF configuration.

Returns Error::Encrypted if the private key is already encrypted.

pub fn algorithm(&self) -> Algorithm

Get the digital signature Algorithm used by this key.

pub fn comment(&self) -> &str

Comment on the key (e.g. email address).

pub fn cipher(&self) -> Cipher

Cipher algorithm (a.k.a. ciphername).

pub fn fingerprint(&self, hash_alg: HashAlg) -> Fingerprint

This is supported on crate feature fingerprint only.

Compute key fingerprint.

Use Default::default() to use the default hash function (SHA-256).

pub fn is_encrypted(&self) -> bool

Is this key encrypted?

pub fn kdf(&self) -> &Kdf

Key Derivation Function (KDF) used to encrypt this key.

Returns Kdf::None if this key is not encrypted.

pub fn key_data(&self) -> &KeypairData

Keypair data.

pub fn public_key(&self) -> &PublicKey

Get the PublicKey which corresponds to this private key.

pub fn random(
    rng: impl CryptoRng + RngCore,
    algorithm: Algorithm
) -> Result<Self>

This is supported on crate feature rand_core only.

Generate a random key which uses the given algorithm.

Returns

• Error::Algorithm if the algorithm is unsupported.

pub fn set_comment(&mut self, comment: impl Into<String>)

This is supported on crate feature alloc only.

Set the comment on the key.
