How do you implement Base64 encoding?
2.1 Encoding Base64 The encoding algorithm is pretty simple: Take three character bytes from the input stream (24bits), divide them into four 6bit parts and convert each 6bit value according to the table above. Repeat this until no more input character bytes are left.
How decode Base64 in SQL?
value( ‘xs:base64Binary(xs:hexBinary(sql:column(“bin”)))’ , ‘VARCHAR(MAX)’ ) Base64Encoding FROM ( SELECT CAST(‘TestData’ AS VARBINARY(MAX)) AS bin ) AS bin_sql_server_temp; — Decode the Base64-encoded string “VGVzdERhdGE=” to get back “TestData” SELECT CAST( CAST(N” AS XML).
How do you find the Base64 encoding?
The length of a Base64-encoded string is always a multiple of 4. Only these characters are used by the encryption: “A” to “Z”, “a” to “z”, “0” to “9”, “+” and “/” The end of a string can be padded up to two times using the “=”-character (this character is allowed in the end only)
What is base64 encoded format?
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. The term Base64 originates from a specific MIME content transfer encoding.
What is Base64 encoded format?
In programming, Base64 is a group of binary-to-text encoding schemes that represent binary data (more specifically, a sequence of 8-bit bytes) in an ASCII string format by translating the data into a radix-64 representation. The term Base64 originates from a specific MIME content transfer encoding.
How to encode string to Base64 in SQL Server?

When to use the binary Base64 option in SQL?
If the BINARY BASE64 option is specified in the query, the binary data is returned in base64 encoding format. By default, if the BINARY BASE64 option is not specified, AUTO mode supports URL encoding of binary data. That is, instead of binary data, a reference to a relative URL to the virtual root…
When to use binary Base64 in auto mode?
If the BINARY BASE64 option is not specified in the query, then by default, AUTO mode supports URL encoding of binary data. A reference to a relative URL to the virtual root of the database is returned. This reference is to the database where the query was executed.
