IV vector initialization with random bytes in do_ssl3_write

[Denis Berezhnoy]

Hi everybody,

I am looking into Openssl1.0.1g source code and I have a question regarding
IV vector initialization with random bytes in do_ssl3_write function.

I am referring to the following code in do_ssl3_write:

    wr->input=p;
    wr->data=p;

    if (eivlen)
        {
    /*    if (RAND_pseudo_bytes(p, eivlen) <= 0)
            goto err; */
        wr->length += eivlen;
        }

    /* ssl3_enc can only have an error on read */
    s->method->ssl3_enc->enc(s,1);


My question is why call for RAND_pseudo_bytes is commented out?

I am not an expert in cryptography but my understanding that Initialization
Vector should be filled with random bytes to prevents repetition in data
encryption.

Could you please clarify?

Best regards,
Denis
