Encryption is a fundamental concept in cryptography that involves the process of converting plaintext (readable and understandable data) into ciphertext (encoded and unintelligible data) using a mathematical algorithm and an encryption key. The primary purpose of encryption is to ensure the confidentiality and privacy of sensitive information during transmission or storage.
In the encryption process:
1. **Plaintext:** This is the original, readable data that is to be protected. It could be a message, a file, or any form of digital information.
2. **Encryption Algorithm:** An encryption algorithm is a set of mathematical rules and procedures that transform the plaintext into ciphertext. Common encryption algorithms include Advanced Encryption Standard (AES), RSA, and Triple DES.
3. **Encryption Key:** The encryption key is a piece of information used by the encryption algorithm to perform the transformation. The key determines the specific pattern and method by which the plaintext is converted into ciphertext. The strength of the encryption often depends on the length and randomness of the key.
4. **Ciphertext:** This is the result of the encryption process—the transformed and encoded data that appears random and is indecipherable without the corresponding decryption key.
Encryption serves several important purposes in the field of cryptography:
- **Confidentiality:** The primary goal of encryption is to keep information confidential and secure from unauthorized access. Even if an unauthorized party intercepts the ciphertext, they should be unable to understand or decipher it without the correct decryption key.
- **Integrity:** Encryption helps ensure the integrity of data by providing a means to detect any unauthorized modifications. If the ciphertext is altered, the decryption process will produce incorrect results, alerting the recipient to potential tampering.
- **Authentication:** In some encryption scenarios, the use of digital signatures or authenticated encryption helps verify the origin and authenticity of the encrypted data.
- **Secure Communication:** Encryption is widely used to secure communication over networks, such as the internet. Protocols like HTTPS (HTTP Secure) use encryption to protect the confidentiality of data transmitted between a web browser and a web server.
- **Data-at-Rest Protection:** Encryption is applied to data stored on devices or servers, ensuring that even if physical access is gained, the data remains protected from unauthorized viewing.
In summary, encryption is a crucial tool in the field of cryptography, providing a means to safeguard the confidentiality, integrity, and authenticity of sensitive information in various digital environments.
SSL is an acronym for Secure Sockets Layer. It is a protocol used for authenticating and encrypting web traffic. For web traffic to be authenticated means that your browser is able to verify the identity of the remote server.

Alfresco DevCon 2019: Encryption at-rest and in-transitToni de la Fuente
To guarantee data integrity and confidentiality in Alfresco, we need to implement authentication and encryption at-rest and in-transit. With micro services proliferation, orchestrating platforms, complex topologies of services and multiple programming languages, there is a demand of new ways to manage service-to-service communication, and in some cases, without the application needing to be aware. In addition to that, compliance requirements around encryption and authentication come to the picture requiring new ways to handle them. This talk will review encryption at-rest solutions for ADBP, and will be also discuss about solutions for encryption and authentication between services. This will be an introduction to service mesh and TLS/mTLS. We will see a demo of ACS running with Istio over EKS along with tools like WaveScope, Kiali, Jaeger, Grafana, Service Graph and Prometheus.
Improving the Secure Socket Layer by Modifying the RSA AlgorithmIJCSEA Journal
Secure Socket Layer (SSL) is a cryptographic protocol which has been used broadly for making secure connection to a web server. SSL relies upon the use of dependent cryptographic functions to perform a secure connection. The first function is the authentication function which facilitates the client to identify the server and vice versa [1]. There have been used, several other functions such as encryption and integrity for the imbuement of security. The most common cryptographic algorithm used for ensuring security is RSA. It still has got several security breaches that need to be dealt with. An improvement over this has been implemented in this paper. In this paper, a modification of RSA has been proposed that switches from the domain of integers to the domain of bit stuffing to be applied to the first function of SSL that would give more secure communication. The introduction of bit stuffing will complicate the access to the message even after getting the access to the private key. So, it will enhance the security which is the inevitable requirement for the design of cryptographic protocols for secure communication.
