With the rapid rise in digital communication, cryptographic algorithms lie at the core of providing data integrity and protection. Identification of the underlying encryption algorithm from a set of encrypted data is pivotal for assessing vulnerability and the strengthening of cryptographic protocols.In this paper, it is proposed to employ an AI classifier model to identify cryptographic algorithms through the integration of machine learning (ML) and natural language processing (NLP) methods. The approach utilizes ciphertext data transformation through TF-IDF vectorization, cryptographic parameter feature engineering, and the application of robust classifiers like XGBoost and Logistic Regression for multi-class classification. Regularization techniques, hyperparameter adjustment, and explainability models (SHAP/LIME) are used by the approach for improving interpretability. The data set, having several encryption schemes, is treated for feature extraction, encoding, and imputation for improving model robustness. Experimental results reveal ensemble learning approaches dominating traditional techniques by a clear margin in detecting algorithms. The study contributes to the field of cybersecurity analytics and introduces the gateway for automated cryptanalysis and AI-driven cryptographic tests. Experimental results reveal ensemble learning approaches dominating traditional techniques by a clear margin in detecting algorithms, with Random Forest achieving the highest accuracy of 88.88%. Future research directions can involve using deep learning architectures like LSTMs and transformers to increase sequence pattern recognition within ciphertext.
