NAME¶
RSA_size, RSA_bits - get RSA modulus sizeSYNOPSIS¶
#include <openssl/rsa.h>int RSA_size(const RSA *rsa);
int RSA_bits(const RSA *rsa);
DESCRIPTION¶
RSA_size() returns the RSA modulus size in bytes. It can be used to determine how much memory must be allocated for an RSA encrypted value.RSA_bits() returns the number of significant bits.
rsa and rsa->n must not be NULL.
RETURN VALUE¶
The size.SEE ALSO¶
