€12-18 EUR / hour

I am looking for someone to add security to my files and database fields through encryption. Specifically, I am looking to encrypt only sensitive files and fields. I have no preference for the type of encryption used, but I am looking for someone with experience in implementing encryption in a language or platform outside of Python or Java. Ideal skills and experience for the job include: - Experience with encryption techniques and best practices - Familiarity with a variety of programming languages and platforms for encryption implementation - Attention to detail when identifying which files and fields should be encrypted - Communication skills to ensure the encryption implementation meets my needs and expectations. Project Description: We are looking for an experienced developer to implement an additional layer of security to the files uploaded by users on our canine boarding intranet. The goal is to encrypt the files using a unique master key generated for each user and store them securely on the server. Additionally, specific fields in the database need to be encrypted to comply with GDPR requirements. Project Requirements: File Encryption: a. Generate a unique encryption key for each user upon registration or account creation. b. Encrypt the uploaded files using the corresponding user's key and store them on the server. c. Decrypt the files for viewing or downloading using the user's logged-in master key. Database Field Encryption: a. Identify sensitive fields in the database tables that require encryption, such as name, address, NIF, contract number, CUPS, invoice number, and street. b. Encrypt the data in the identified fields using the corresponding user's key and store them in the database. c. Decrypt the data upon accessing and present it in a readable format for the user. Deliverables: File Encryption and Decryption Functions: Code to encrypt files uploaded by users using the user's corresponding key. Code to decrypt files for viewing or downloading using the user's master key. Database Field Encryption and Decryption Functions: Code to encrypt data in the sensitive fields using the user's corresponding key. Code to decrypt the data upon accessing and present it in a readable format. We welcome proposals from developers with experience in web application security and data encryption. Please include relevant examples of previous work when submitting your proposal. Note: The provided code example is a starting point for implementing file encryption and decryption. You may need to adjust the code to fit your specific environment and database characteristics. This applies to an intranet built in PHP where files are uploaded and stored insecurely, and we want to add an encryption layer to these files and specific fields in the database. ADDING SECURITY TO FILES AND DATABASE FIELDS THROUGH ENCRYPTION Using a script similar to the one attached, encrypt the files uploaded by users to store them on the server in an encrypted form using a unique master key generated at the time of user registration or account creation. This master key will be stored in the database, in the 'tbl_member' table, in the 'master_key' field (MD5). When viewing or downloading the file, it will be decrypted using the logged-in user's master key. By doing this, we ensure that if access to the server is obtained through FTP or any other means, personal files will be encrypted and not visible. We will apply the same process to specific database fields due to GDPR requirements. Specific fields to be encrypted: In the 'tbl_member' table: Name Surname Address NIF In the 'tbl_contract' table: Contract number In the 'tbl_invoice' table: CUPS Invoice number In the 'tbl_property' table: Street Please place the code in the following sections: Inmuebles -> Urbanización y Planos Inmuebles -> Imágenes Contratos -> [Add code here] Facturas -> [Add code here]
