Re: Using BIO_f_base64 on in-memory data

Never mind my question. Apparently the Base64 interpreter only accepts data if it's newline-terminated. Sorry for the bother. On 21-Jul-09, at 5:59 PM, Jeremy R. wrote: Hello: I'm trying to do something that should be fairly simple: read Base64- encoded data in memory block A an

Using BIO_f_base64 on in-memory data

When it's -1, BIO_should_retry() and BIO_should_read() both return true but BIO_should_write() returns false. I don't know where to go from here. I'm an OpenSSL newbie, and I'd appreciate any help you could offer. My Google searches haven't turned up anything u

Re: General Question

They are two different network protocols which both implement cryptography. OpenSSL is primarily used by developers behind the scenes and not directly by users (though there is an "openssl" command-line tool that exposes many of OpenSSL's capabilities). I assume the "command prompt featur
