WebA tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. WebNever use ECB! It is insecure. I recommend an authenticated encryption mode, like EAX or GCM. If you can't use authenticated encryption, use CBC or CTR mode encryption, and then apply a MAC (e.g., AES-CMAC or SHA1-HMAC) to the resulting ciphertext.
