SSL/TLS adalah metode enkripsi (cryptographic protocol), bisa pakai SSL
atau TLS.
STARTTLS adalah mail command (protocol command) untuk mengubah
(switching) dari non secure/plain ke Secure SSL atau TLS.

SSL and TLS both provide a way to encrypt a communication channel
between two computers (e.g. your computer and our server). TLS is the
successor to SSL and the terms SSL and TLS are used interchangeably
unless you're referring to a specific version of the protocol.

STARTTLS is a way to take an existing insecure connection and upgrade it
to a secure connection using SSL/TLS. Note that despite having TLS in
the name, STARTTLS doesn't mean you have to use TLS, you can use SSL.

Understanding SSL, TLS, and STARTTLS Email Encryption

SSL, TLS, and STARTTLS refer to standard protocols used to secure email
transmissions.

SSL (Secure Sockets Layer) and its successor, Transport Layer Security
(TLS), provide a way to encrypt a communication channel between two
computers over the Internet. In most cases, the terms SSL and TLS can be
used interchangeably unless you’re referring to a specific version of
the protocol.

Because TLS and SSL are application-layer protocols, senders and
receivers need to know that they are being used to encrypt emails during
transit. That’s where STARTTLS comes into play.

STARTTLS is an email protocol command that tells an email server that an
email client, including an email client running in a web browser, wants
to turn an existing insecure connection into a secure one. (By the way,
the use of “TLS” in the STARTTLS command name does not mean that it only
works with the TLS security protocol. It works with SSL too.)

SSL and TLS

SSL and TLS are cryptographic protocols, both provide a way to encrypt
communication channel between two machines over the Internet (e.g.
client computer and a server). SSL stands for Secure Sockets Layer and
current version is 3.0. TLS stands for Transport Layer Security and the
current version is 1.2. TLS is the successor to SSL. The terms SSL and
TLS can be used interchangeably, unless you’re referring to a specific
protocol version.

Version numbering is inconsistent between SSL and TLSs. When TLS took
over SSL as the preferred protocol name, it began with a new version
number. The ordering of protocols in terms of oldest to newest is:
SSLv2, SSLv3, TLSv1.0, TLSv1.1, TLSv1.2.
STARTTLS and STLS

STARTTLS is a protocol command, that is issued by an email client. It
indicates, that the client wants to upgrade existing, insecure
connection to a secure connection using SSL/TLS cryptographic protocol.
STARTTLS command name is used by SMTP and IMAP protocols, whereas POP3
protocol uses STLS as the command name.
