Sažetak	Symmetric key cryptanalysis is the study of attacks against symmetric encryption algorithms (such as DES, AES, and stream ciphers) to evaluate their security and identify weaknesses. Classical techniques include differential cryptanalysis and linear cryptanalysis, which have shaped the design of modern ciphers and remain essential tools for cryptographers assessing algorithm robustness.	The Secure Hash Algorithm (SHA) is a family of cryptographic hash functions standardized by NIST starting in 1993. SHA functions produce fixed-length digests from arbitrary-length input data, serving as a fundamental building block for digital signatures, message authentication, and data integrity verification across security-critical applications.
