The development of digital technology has transformed document formats from printed to digital forms. Despite providing convenience, digital documents are vulnerable to manipulation and forgery, thus requiring mechanisms to maintain document authenticity and integrity. Digital signatures represent one method that can be used to preserve authenticity in digital documents. This research implements digital signatures using a combination of RSA and SHA-512 algorithms. RSA was selected due to its advantages in prime number factorization complexity, while SHA-512 is used because it produces hash values of 512-bit length. The data used in this research consists of digital documents in PDF, DOCX, and XLSX formats obtained from the website https://examplefile.com/, totaling 15 sample data. The research results show that the combination of both algorithms produces an avalanche effect value with an average of 67.41%, which indicates good sensitivity levels to input changes. The research also found that key value size and digital document file size are correlated with each other; the larger the key value and document size, the longer the processing time required, with the fastest signing time being 1.308 seconds and the longest 277.860 seconds, while the fastest verification time is 1.272 seconds and the longest 1,079.491 seconds.
