Encryption can help protect data you send, receive, and store, using a device. That can include text messages stored on your smartphone, running logs saved on your fitness watch, and banking information sent through your online account.
Encryption is the process that scrambles readable text so it can only be read by the person who has the secret code, or decryption key. It helps provide data security for sensitive information.
Vast amounts of personal information are managed online and stored in the cloud or on servers with an ongoing connection to the web. It’s nearly impossible to do business of any kind without your personal data ending up in an organization’s networked computer system, which is why it’s important to know how to help keep that data private.
Encryption plays an essential role.
How does encryption work?
Encryption is the process of taking plain text, like a text message or email, and scrambling it into an unreadable format — called “cipher text.” This helps protect the confidentiality of digital data either stored on computer systems or transmitted through a network like the internet.
When the intended recipient accesses the message, the information is translated back to its original form. This is called decryption.
To unlock the message, both the sender and the recipient have to use a “secret” encryption key — a collection of algorithms that scramble and unscramble data back to a readable format.
Symmetric and asymmetric encryption: What’s the difference?
An encryption key is a series of numbers used to encrypt and decrypt data. Encryption keys are created with algorithms. Each key is random and unique.
There are two types of encryption systems: symmetric encryption and asymmetric encryption. Here’s how they’re different.
Symmetric encryption uses a single password to encrypt and decrypt data.
Asymmetric encryption uses two keys for encryption and decryption. A public key, which is shared among users, encrypts the data. A private key, which is not shared, decrypts the data.
Types of Encryption
There are several types of encryption, each developed with different needs and security needs in mind. Here are the most common examples of encryption.
Data Encryption Standard (DES)
Data Encryption Standard is considered a low-level encryption standard. The U.S. government established the standard in 1977. Due to advances in technology and decreases in the cost of hardware, DES is essentially obsolete for protecting sensitive data.
Triple DES
Triple DES runs DES encryption three times. Here’s how it works: It encrypts, decrypts, and encrypts data — thus, “triple.” It strengthens the original DES standard, which became regarded as too weak a type of encryption for sensitive data.
RSA
RSA takes its name from the familial initials of three computer scientists. It uses a strong and popular algorithm for encryption. RSA is popular due to its key length and therefore widely used for secure data transmission.
Advanced Encryption Standard (AES)
Advanced Encryption Standard is the U.S. government standard as of 2002. AES is used worldwide.
TwoFish
Encryption Text Into Picture
Twofish is considered one of the fastest encryption algorithms and is free for anyone to use. It’s used in hardware and software.
Using encryption via SSL
Most legitimate websites use what is called “secure sockets layer” (SSL), which is a form of encrypting data when it is being sent to and from a website. This keeps attackers from accessing that data while it is in transit.
Look for the padlock icon in the URL bar, and the “s” in the “https://” to make sure you are conducting secure, encrypted transactions online.
It’s a good idea to access sites using SSL when:
You store or send sensitive data online. If you use the internet to carry out tasks such as filing your taxes, making purchases, renewing your driver’s license, or conducting any other personal business, visiting sites using SSL is a good idea.
Your work requires it. Your workplace may have encryption protocols, or it may be subject to regulations that require encryption. In these cases, encryption is a must.
3 reasons why encryption matters
Why is encryption important? Here are three reasons:
1. Internet privacy concerns are real
Encryption helps protect your online privacy by turning personal information into “for your eyes only” messages intended only for the parties that need them — and no one else.
You should make sure that your emails are being sent over an encrypted connection, or that you are encrypting each message.
Most email clients come with the option for encryption in their Settings menu, and if you check your email with a web browser, take a moment to ensure that SSL encryption is available.
2. Hacking is big business
Cybercrime is a global business, often run by multinational outfits.
Many of the large-scale data breaches that you may have heard about in the news demonstrate that cybercriminals are often out to steal personal information for financial gain.
3. Regulations demand it
The Health Insurance Portability and Accountability Act (HIPAA) requires healthcare providers to implement security features that help protect patients’ sensitive health information online.
Institutions of higher learning must take similar steps under the Family Education Rights and Privacy Act (FERPA) to protect student records.
Retailers must contend with the Fair Credit Practices Act (FCPA) and similar laws that help protect consumers.
Encryption helps businesses stay compliant with regulatory requirements and standards. It also helps protect the valuable data of their customers.
How ransomware uses encryption to commit cybercrimes
Encryption Text Messages
Encryption is designed to protect your data, but encryption can also be used against you.
For instance, targeted ransomware is a cybercrime that can impact organizations of all sizes, including government offices. Ransomware can also target individual computer users.
How do ransomware attacks occur? Attackers deploy ransomware to attempt to encrypt various devices, including computers and servers. The attackers often demand a ransom before they provide a key to decrypt the encrypted data. Ransomware attacks against government agencies can shut down services, making it hard to get a permit, obtain a marriage license, or pay a tax bill, for instance.
Targeted attacks are often aimed at large organizations, but ransomware attacks can also happen to you.
Here are some tips to help protect your devices against ransomware attacks and the risk of having your data encrypted and inaccessible.
Install and use trusted security software on all your devices, including your mobile phone.
Keep your security software up to date. It can help protect your devices against cyberattacks.
Update your operating system and other software. This can patch security vulnerabilities.
Avoid reflexively opening email attachments. Why? Email is one of the principal methods for delivering ransomware.
Be wary of any email attachment that advises you to enable macros to view its content. If you enable macros, macro malware can infect multiple files.
Back up your data to an external hard drive. If you’re the victim of a ransomware attack, you’ll likely be able to restore your files once the malware has been cleaned up.
Consider utilizing cloud services. This can help mitigate a ransomware infection, since many cloud services retain previous versions of files, allowing you to “roll back” to the unencrypted form.
Don’t pay the ransom. You could pay a ransom in hopes of getting your files back — but you might not get them back. There’s no guarantee the cybercriminal will release your data.
Encryption is essential to help protect your sensitive personal information. But in the case of ransomware attacks, it can be used against you. It’s smart to take steps to help you gain the benefits and avoid the harm.

As you see this implementation is using openssl instead of mcrypt and the result of the encryption/decryption is not compatible with each other. The mcrypt function will be deprecated feature in PHP 7.1.x
What is AES encryption?
It is a webtool to encrypt and decrypt text using AES encryption algorithm. You can chose 128, 192 or 256-bit long key size for encryption and decryption. The result of the process is downloadable in a text file.
How to use AES encryption?
If you want to encrypt a text put it in the white textarea above, set the key of the encryption then push the Encrypt button. The result of the encryption will appear in base64 encoded to prevent character encoding problems. If you want to decrypt a text be sure it is in base64 encoded and is encrypted with AES algorithm! Put the encrypted text in the white textarea, set the key and push the Decrypt button.
When is helpful to use AES encryption?
When you want to encrypt a confidential text into a decryptable format, for example when you need to send sensitive data in e-mail. The decryption of the encrypted text it is possible only if you know the right password.
What is AES encryption?
AES (acronym of Advanced Encryption Standard) is a symmetric encryption algorithm. The algorithm was developed by two Belgian cryptographer Joan Daemen and Vincent Rijmen. AES was designed to be efficient in both hardware and software, and supports a block length of 128 bits and key lengths of 128, 192, and 256 bits.
How secure is AES encryption algorithm?
Encryption Text
AES encryption is used by U.S. for securing sensitive but unclassified material, so we can say it is enough secure.
