M:Windows.Security.Cryptography.CryptographicBuffer.DecodeFromBase64String(System.String)	winrt method

Windows.Security.Cryptography.CryptographicBuffer.DecodeFromBase64String

-description

Decodes a string that has been base64 encoded.

-parameters

-param value

Base64 encoded input string.

-returns

Output buffer that contains the decoded string.

-remarks

Base64 processes data as 24-bit groups, mapping each group to four encoded 8-bit characters. Base64 encoding is sometimes referred to as 3-to-4 encoding. Each 6 bits of the 24-bit group is used as an index into a mapping table (the base64 alphabet) to obtain a character for the encoded data.
