A convenience wrapper struct for dealing with URL-safe Base64 encoded globally unique identifiers (GUID), making a shorter string value (22 vs 36 characters long). As of version 2.0.0, `ShortGuid` performs a sanity check when decoding strings to ensure they haven't been tampered with, i.e. allowing the end of a Base64 string to be tweaked where it still produces that same byte array to create the underlying Guid. Effectively there is "unused space" in the Base64 string which is ignored, but will now result in an `FormatException` being thrown. ShortGuid will never produce an invalid string, however if one is supplied, it could result in an unintended collision where multiple URL-safe Base64 strings can point to the same Guid. To avoid this uncertainty, a round-trip check is performed to ensure a 1-1 match with the input string. Stick with version 1.1.0 if you require the old behaviour with opt-in strict parsing.
A standards-compliant implementation of url-safe base64 encode/decode for .NET projects with Span optimizations.
Multiformat base encodings

BaseNEncodings.Net is a general base16, base32, base64 encodings library for .NET 2.0+, which is according to RFC 4648. Full details can be found on the project page here: https://github.com/wallf/BaseNEncodings.Net
Get file size from base64 string
Parser for Apple Receipt that represented in base64 and encoded with ASN.1
Performs base64url encoding which differs from regular base64 encoding as follows. Padding is skipped so the pad character '=' doesn't have to be percent encoded. The 62nd and 63rd regular base64 encoding characters ('+' and '/') are replace with ('-' and '_') The changes make the encoding alphabet file and URL safe.
Standards based implementations of various Base32 and Base64 encoding/decoding methods. These are designed to encode binary data to plain text, and decode the resulting text back to the original binary. This is useful when you need to transfer binary data through technologies that only support text (such as including binary security tokens in URLs). Base32Url encodes with only the characters A to Z and 2 to 7. No hyphens, underscores, pluses, slashes or equals are used, making it usable as a URL token in almost all circumstances. Base32Url also supports custom alphabets. A custom case sensitive alphabet with only consonant (non vowel) characters can be used to ensure your tokens do not contain accidental profanities. The following is an example that avoids vowels, the letter L and has no numeric characters: BCDFGHKMNPQRSTVWXYZbcdfghkmnpqrs. Base64Url is more compact than Base32Url and it is almost always usable as a URL token or file-name. The only non alpha-numeric characters Base64Url contains are the hyphen (-) and underscore (_) characters, neither of these need further encoding for use in URLs or file-names. * Supports standard Base32 with padding characters (=) per Base32 from RFC 4648. * Supports the Base32 extension / alternate alphabet z-base-32 and the asymmetric crockford encoding.
With support for URL-safe encoding, this provides helpers methods for encoding and decoding base64, in multiple forms.

Smdn.Fundamental.PrintableEncoding.Base64.dll
Implements Base-64 encoding with URL and filename safe alphabet. Add this package to your core library, so it would get the source code of this module without installing a binary dependency. Then proceed with using corresponding functionality from Atom.Util namespace, like if it was installed using binary assembly. Check out GitHub for more docs and usage examples.
