How To Send Documents Securely

Speed and efficiency are essential to the modern business world. With digital communication, you can send documents, contracts, invoices, and other files quickly. However, it’s not just about sending them quickly. It’s also about keeping them safe from prying eyes. Here are some tips for sending documents securely via email.

What Is Document Encryption?

Document encryption is a process of transforming readable data into an unreadable format. This is done using an encryption algorithm and a secret key, which can be decrypted only with the correct key. The purpose of document encryption is to protect information from being accessed by unauthorized individuals.

There are several different types of document encryption algorithms that are used today. The most common include the Advanced Encryption Standard (AES), the Data Encryption Standard (DES), and the Rivest-Shamir-Adleman (RSA) algorithm. AES is considered the most secure of these three and is often used by government organizations and businesses to protect sensitive information. 

DES is less secure than AES but is still widely used, particularly in financial institutions. RSA is the least secure of the three but is still used in some situations where security is not as critical.

When choosing an encryption algorithm, it is vital to consider the level of security that you need. If you encrypt very sensitive information, you need to use a more secure algorithm such as AES. If you encrypt less sensitive information, you can use a less secure algorithm such as DES or RSA.

Once you have selected an encryption algorithm, you must generate a secret key. This key should be confidential and not be shared with anyone else. If someone else obtains your key, they can decrypt your data. Once you have generated a key, you can encrypt your data using the algorithm and the key.

To decrypt the data, you will need to have the correct key. If you do not have the key, you will be unable to decrypt the data. That is why it is crucial to keep the key secret and never share it with anyone else.

Problems With Sending Documents Via Email

One of the most common problems with sending documents via email is that third-party attackers can intercept them. Even if you are using a secure connection and encryption, there is still a risk that a knowledgeable attacker could decrypt the document. This is especially true if you use an unsecured connection or send the document to a non-encrypted email address.

Another problem with sending documents via email is that they can be lost in transit. This can happen if the email server crashes or the email is incorrectly delivered to the wrong recipient. Additionally, emails can be accidentally deleted or blocked by spam filters.

Finally, sending documents via email can also be problematic because it is often difficult to track who has accessed the document. This can make it difficult to determine if the document has been tampered with or if unauthorized access has occurred.

How To Send Documents Securely Via Email

When sending documents via email, it’s important to take steps to ensure that your information is kept secure. Here are some tips for sending documents securely via email:- 

Use a Secure Email Service: Look for an email service that offers features like encrypted messages and file attachments. This will help to keep your information safe from prying eyes.

Avoid Using Public Wi-Fi: When sending documents over email, avoid using public Wi-Fi hotspots as they are not secure. Instead, use a private or home Wi-Fi connection.

Don’t Send Sensitive Information In Plain Text: If your document contains sensitive information, encrypt it before sending it. This will help to keep the data safe from interception.

By following these tips, you can help to ensure that your documents are sent securely via email.

There are a few other ways to send documents securely via email. One way is to use a secure email service like O-Mail. O-Mail encrypts your email messages and attachments so that only the intended recipient can read them.

Based on your preferences and needs, you can choose which method to use. If you send sensitive information, you may use a secure email service like O-Mail.


Sending documents securely via email is a process that requires a few steps. By encrypting your document, creating a strong password, and verifying the recipient’s identity, you can send your document safely via email and protect your sensitive information from prying eyes.
