# [−][src]Struct nettle::rsa::PrivateKey

A private RSA key.

## Implementations

`impl PrivateKey`

[src]

`pub fn new<'a, O: Into<Option<&'a [u8]>>>(`

d: &[u8],

p: &[u8],

q: &[u8],

inv: O

) -> Result<Self>

[src]

d: &[u8],

p: &[u8],

q: &[u8],

inv: O

) -> Result<Self>

Creates a new private key with the private exponent `d`

and the two primes `p`

/`q`

.
If the inverse `inv`

for `q`

in Z_p is `None`

the function computes it.

# Notes

This function does time-variable computation on the private key that may leak it. See
`new_crt`

for a time-constant way to create a PrivateKey.

`pub fn new_crt<'a, O: Into<Option<&'a [u8]>>>(`

dp: &[u8],

dq: &[u8],

p: &[u8],

q: &[u8],

inv: O

) -> Result<Self>

[src]

dp: &[u8],

dq: &[u8],

p: &[u8],

q: &[u8],

inv: O

) -> Result<Self>

Creates a new private key with the two primes `p`

/`q`

. The private exponent `d`

is given as
`dp = d mod p - 1`

and `dq = d mod q - 1`

. If the inverse `inv`

of `q`

in Z_p is `None`

the function computes it.

# Notes

If `inv`

is `None`

the function does time-variable computation on the private key that may leak it.

`pub fn public_key(&self) -> Result<PublicKey>`

[src]

Computes the public key to this private key. This only works if the private key was created
with `new`

instead of `new_crt`

.

# Notes

This function does time-variable computation on the private key that may leak it.

`pub fn as_rfc4880(&self) -> (Box<[u8]>, Box<[u8]>, Box<[u8]>)`

[src]

Returns the tuple `a`

, `b`

, `c`

. `a`

and `b`

are the two RSA primes `p`

/`q`

with `a`

< `b`

and
`c = a^-1 mod b`

.

`pub fn primes(&self) -> (Box<[u8]>, Box<[u8]>)`

[src]

Returns the primes `p`

/`q`

as big endian integers.

`pub fn d_crt(&self) -> (Box<[u8]>, Box<[u8]>, Box<[u8]>)`

[src]

Returns the private exponent `d`

as pair of big endian integers `dp = d mod p - 1`

and `dq = d mod q - 1`

and the inverse of `q`

in Z_p as third value.

`pub fn d(&self) -> Box<[u8]>`

[src]

Returns the private exponent `d`

as big endian integer.
