I would like to ask whether it is possible in OP-TEE to use different algorithms for the main hash and the MGF1 hash in RSA OAEP. I would like to decrypt data using OP-TEE when the data was encrypted ...

Hashing transforms data into a fixed-length cryptographic fingerprint that ensures integrity and authenticity. Every block in a blockchain contains its own hash and the previous block’s hash, forming ...

Cryptography secures communication in banking, messaging, and blockchain. Good algorithms (AES, RSA, ECC, SHA-2/3, ChaCha20) are secure, efficient, and widely trusted. Bad algorithms (DES, MD5, SHA-1, ...

Abstract: Cryptographic hash functions are essential for securing data integrity in systems such as digital signatures, blockchain networks, and secure communication protocols. Among the widely ...
