You wouldn't want to base64 encode twice, because the single decoding would also result in something invalid. These are the methods that I use to both encode and decode in my daily work. ghost mentioned this issue on Aug 13, 2018. In this article, I will share both a simple and a slightly more advanced understanding of Base64 encoding. There are other ways to construct userdata that will already be base64 encoded, so the behaviour of Terraform aws provider is correct here, it needs to be up to the end user whether or not to apply the encoding. : 1 error (s) occurred: awslaunchtemplate.test: InvalidUserData.Malformed: Invalid BASE64 encoding of user data. If you are passing plaintext into userdata, suggestion is the right thing to do. It covers the case of both uncompressed and compressed bitcoin addresses (just changing compress. I'd like to contribute with this implementation of bitcoin address from public key. I tried decoding mkdir /tmp/test, (the spaces and newlines are skipped by base64 decoding) and it gives Gbf^ This page is useful What happens when you try and run Gbf^ will depend on the platform, but will probably an error like "command not found". If the public key were correct (see Mark's answer), the code is not complete (lacks signature) and contains a hash of an ASCII hexdigest which is not correct. When the userdata is executed on the EC2 instance it will be decoded. So while the terraform stack may have planned/applied successfully, the userdata script probably failed. Craig Wright has recovered an old (and real) Satoshi's signature and tried to provide it as a new signature to validate his identity. The scam is not based on a cryptographic attak but on what is signed. I strongly suspect that your userdata would be decoded into something invalid. Short version: the signature is correct, it is a real signature and therefore it is possible to verify it with one's favourite software. It appears to work because your userdata doesn't use any characters outside those used in base64 encoding. In no case it should not be confused with “encryption” and “decryption” which are used to protect data, while Base64 doesn’t offer any protection.I don't think your test case really does succeed, even though you don't see the same error. And since we are talking about terms, remember that the conversation of text to Base64 is called “encoding” and the reverse process is called “decoding”. However, from a technical point of view, this process is called “conversation”, therefore, never call it a “Base64 translator”. Well, by and large, it really “translates” the text into another form. It may seem funny, but some people call the “Base64 converter” a “Base64 translator”. Nevertheless, if you’re missing some Base64 encoding or decoding features, please let me know. I hope that I managed to develop all the necessary converters that meet your needs. They are also simple and free, but they are sharpened for certain tasks. If so, please check the following online convertors. To review, open the file in an editor that reveals hidden Unicode characters. Perhaps this option does not suit your needs, and you want to encode text or decode Base64 using other variations of this algorithm. This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below. Please note that this Base64 converter supports only “main standard” and decodes the data in strict mode.
