Some Blogspot blogs are built for commercial purposes; others are simply to share and exchange information, and/or to link to other websites. Some can even use Blogspot to store their own information (for free) and then share it with users of their choice.
Draft
If you want to keep your post or page for yourself, you can simply put it into Draft. If some day, you change your mind; you can make it public via Publish. On your Blogger dashboard, you can click on the wing icon to change Draft to Publish, and vice versa. You can choose to exclude your drafts from the Table of Contents.
Private Blog
By default, your blog is public. Blogger allows you to
control your blog privacy, via Settings > Permissions > Reader access:
· Private to
authors: All
authors of your blog can access and read it, if your blog has invited authors
(via “Invite more authors”).
· Custom readers: Only the readers you invite can access and read your blog (via “Invite more readers”)
All invites are by means of email as shown below
Note that this setting applies to
the entire blog.
Also, if you don’t want your blog
to be seen by search engines, you can simply select Settings > Privacy >
Visible to search engines (OFF).
Semi-private Blog
There are instances where certain portions of your blog contain sensitive information, and you want viewer’s restriction. Below are various kinds of sensitive information:
Personally Identifiable Information (PII)
Data that can uniquely identify someone:
- Full name (when linked
to other private info)
- Home address or mailing
address
- Date of birth
- Social Insurance Number
(Canada), Social Security Number (U.S.), or similar ID numbers
- Passport or driver’s
license number
- Personal phone numbers
or private email addresses
- Bank account or credit
card numbers
Sensitive Personal Attributes
Information about personal characteristics or status:
- Health conditions,
medical history, or disabilities
- Mental health status or
therapy records
- Sexual orientation or
sexual history
- Religious beliefs or
practices
- Political opinions or
affiliations

identity (if linked to personal identity)

proprietary formulas

Information
About Vulnerable Groups
Especially protected under privacy laws:
- Children’s names,
photos, or school information
- Locations of shelters,
foster homes, or safe houses
- Refugee or asylum
seeker identities
You can use password to protect
such information; and your password should not show up in “View page source”.
You must provide your desired readers with your password, and the password must
be difficult to be decoded. Furthermore, it would be safer not to use the same
password for every portion of your blog (or for all your blogs).
The above can be achieved in 3
steps:
1) Using HTML
view, define the text to be password-protected in your post;
2) Generate
password offline;
3) Write
HTML/CSS/JavaScript code to allow viewers to input password, check it against
your own password generated in 2), and decide whether your password-protected
text should be revealed.
Password Generation
The password must be encrypted and difficult to decrypt, for which you would need a password generator. The number of your input data and the sophistication of the algorithm used by the generator will determine the level of security. The final password can be:
· Maximum
Security Password (20 ASCII printable characters)
· Long Password
(14 ASCII printable characters)
· Medium
Password (8 ASCII printable characters)
· Short Password
(4 ASCII printable characters)
· Basic Password
(8 alphanumeric characters)
· PIN (4 digits)
“Master Password” is the well-known algorithm to
generate secure passwords. The passwords are not stored on disk or in the cloud;
but are regenerated every time from information entered by the user. An example
of Master Password is illustrated below, using master_password_generator.html:
With the following input:
Master password = hello world
Username = kody
Site name = abc@gmail.com (this is required)
Template / length =16
the above generator produces the
password "Dh7#ZE$-T)u<?DUv".
The above password is highly
secure. However, for the viewers to be able to generate the same password as
yours, you must provide all 4 input boxes and inform them about the data to
enter. This complexity might discourage your viewers from viewing your secret
text.
If you simply want obfuscation, not true protection, you can use a simpler encrypted password generator which requires only 1 input from the viewers. The following illustration is from Simple Password generator.html:
where the boxes Secret Content (Don’t
show my secret to your friends) and Password (Oct2045) have been filled with
viewer’s inputs.
If you click the “Generate” button,
the following code will be generated:
<!-- Load CryptoJS library
-->
<script
src="https://cdnjs.cloudflare.com/ajax/libs/crypto-js/4.1.1/crypto-js.min.js"></script>
<p><b>This post is protected. Enter password:</b></p>
<input type="password"
id="pass">
<button
onclick="decryptContent()">Unlock</button>
<div id="protected" style="display:none; margin-top:10px; padding:10px; border:1px solid #ccc; background:#f9f9f9;"></div>
<script>
function decryptContent() {
var pass = document.getElementById("pass").value;
var encrypted = "U2FsdGVkX1+vaSOkktVJR8Q943O9+JxuSCdKE3HAIM/FgjsqKKTObjS+w9Nd9Jm8eeDERzr70FRjRDwEjafloQ==";
try {
var bytes =
CryptoJS.AES.decrypt(encrypted, pass);
var originalText = bytes.toString(CryptoJS.enc.Utf8);
if (originalText) {
document.getElementById("protected").innerHTML = originalText;
document.getElementById("protected").style.display =
"block";
} else {
alert("Wrong password!");
}
} catch (e) {
alert("Error decrypting.");
}
}
</script>
Your encrypted password is
“U2FsdGVkX1+vaSOkktVJR8Q943O9+JxuSCdKE3HAIM/FgjsqKKTObjS+w9Nd9Jm8eeDERzr70FRjRDwEjafloQ==”
If you run this code, you’ll see
the following
Unless your viewers had the
password generator in Simple Password generator.html, they would not
know how the password “Oct2045” was encrypted.
Finally, in the following paragraph,
an encrypted password based on the above one-input password generation is used
to hide a “secret information”. Would you like to see it?
Most, if not all, auto translators have difficulty to translate a commonly used phrase in South Vietnamese “nhiêu, nhiều”; for example, “much” in Google Translate, “many, a lot” in Microsoft Bing, “multiple, many” in iTranslate, “many, many” in Translate.com, etc. To see the true meaning of the above phrase and its English translation, enter password in the box below.
