blowfish sha-256 hmac
Here are several online crypto tools. Please feel free to use them as online resources to encrypt and decrypt data, generate hashes, and generate HMAC’s.
encrypt and decrypt using Blowfish
generate SHA-2 hashes
generate Hash-based Message Authentication Codes
encode and decode Base64
Each of these cryptographic algorithms was chosen deliberately. Each is the best of its kind. While other algorithms are available, these are the ones that are both industrial strength and able to resist aggressive cryptanalysis. Blowfish is a fast and secure. It was designed as a DES replacement by Bruce Schneier. SHA-2 is a newer class of hash functions that includes SHA-256. Why didn’t I use SHA-512? I’m waiting for SHA-3.
