Yeah, this. Didn't realize people actually saw this as an issue worthy of worrying about. The Matasano Crypto Challenges I did way back when were in Go and the ones involving ECB were just done as for loops over the standard library AES Decrypt/Encrypt methods, something like this: for i := 0; i < blockCount; i++ { start := i * blockLength end := start + blockLength aes.Decrypt(decryptBuffer, input[start:end]) output = append(output, decryptBuffer) }
