| Details |
Base 64 is an industry encoding method whose encoded characters are determined by using a positional scheme that uses only ASCII characters. Several Base 64 encoding schemes have been defined by the industry for specific uses, such as e-mail or content masking. SAS maps positions 0 - 61 to the characters A - Z, a - z, and 0 - 9. Position 62 maps to the character +, and position 63 maps to the character /.
The following are some uses of Base 64 encoding:
-
embed binary data in an XML file
-
encode passwords
-
encode URLs
The '=' character in the encoded results indicates that the results have been padded with zero bits. In order for the encoded characters to be decoded, the '=' must be included in the value to be decoded.
