     8  # `base64gzip` Function
     9  
    10  `base64gzip` compresses a string with gzip and then encodes the result in
    11  Base64 encoding.
    12  
    13  Terraform uses the "standard" Base64 alphabet as defined in
    14  [RFC 4648 section 4](https://tools.ietf.org/html/rfc4648#section-4).
    15  
    16  Strings in the Terraform language are sequences of unicode characters rather
    17  than bytes, so this function will first encode the characters from the string
    18  as UTF-8, then apply gzip compression, and then finally apply Base64 encoding.
    19  
    20  While we do not recommend manipulating large, raw binary data in the Terraform
    21  language, this function can be used to compress reasonably sized text strings
    22  generated within the Terraform language. For example, the result of this
    23  function can be used to create a compressed object in Amazon S3 as part of
    24  an S3 website.

    28  * [`base64encode`](/language/functions/base64encode) applies Base64 encoding _without_
    29    gzip compression.
    30  * [`filebase64`](/language/functions/filebase64) reads a file from the local filesystem
    31    and returns its raw bytes with Base64 encoding.
