Web15 hours ago · I'm looking for some solutions with trying to encrypt a value using Java 8 AES/ECB/PKCS5Padding vs. using .NET AesCryptoServiceProvider using the same secret key between both implementations. Should the two methods using the same secret key produce the same encrypted values? Below is the Java used to encrypt data: Any cryptographic hash function, such as SHA-2 or SHA-3, may be used in the calculation of an HMAC; the resulting MAC algorithm is termed HMAC-X, where X is the hash function used (e.g. HMAC-SHA256 or HMAC-SHA3-512). The cryptographic strength of the HMAC depends upon the cryptographic strength of the underlying hash function, the size of its hash output, and the size and quality of the key.
