atob(): decodes a Base64-encoded string ("atob" should be read as "ASCII to binary"). n) endif BIOprintf(bioerr, -base64 - base64 encode outputn) BIOprintf(bioerr, -hex - hex encode outputn).btoa(): creates a Base64-encoded ASCII string from a "string" of binary data ("btoa" should be read as "binary to ASCII").In JavaScript there are two functions respectively for decoding and encoding Base64 strings: One common application of Base64 encoding on the web is to encode binary data so it can be included in a data: URL. Base64 is commonly used in a number of applications including email via MIME, and storing complex data in XML. This is to ensure that the data remain intact without modification during transport. Vice versa while decrypting, zlib will be applied first.
The term Base64 originates from a specific MIME content transfer encoding.īase64 encoding schemes are commonly used when there is a need to encode binary data that needs to be stored and transferred over media that are designed to deal with ASCII. After a file is encrypted (and maybe base64 encoded) it will be compressed via zlib. Base64 is a group of similar binary-to-text encoding schemes that represent binary data in an ASCII string format by translating it into a radix-64 representation.
