pseudo_bytes(p1)

public

Generates string with length number of pseudo-random bytes.

Pseudo-random byte sequences generated by ::pseudo_bytes will be unique if they are of sufficient length, but are not necessarily unpredictable.

Example:

  OpenSSL::Random.pseudo_bytes(12)
  => "..."

static VALUE
ossl_rand_pseudo_bytes(VALUE self, VALUE len)
{
    VALUE str;
    int n = NUM2INT(len);

    str = rb_str_new(0, n);
    if (!RAND_pseudo_bytes((unsigned char *)RSTRING_PTR(str), n)) {
        ossl_raise(eRandomError, NULL);
    }

    return str;
}
