Struct openssl::bn::BigNumContext

pub struct BigNumContext(_);

Temporary storage for BigNums on the secure heap

BigNum values are stored dynamically and therefore can be expensive to allocate. BigNumContext and the OpenSSL BN_CTX structure are used internally when passing BigNum values between subroutines.

Implementations

impl BigNumContext

pub fn new() -> Result<BigNumContext, ErrorStack>

Returns a new BigNumContext.

See OpenSSL documentation at BN_CTX_new.

pub fn new_secure() -> Result<BigNumContext, ErrorStack>

Returns a new secure BigNumContext.

See OpenSSL documentation at BN_CTX_secure_new.
