Data transformation functions

The data transformation functions change data into a different representation for the purposes of security, space savings, or transmission time savings.

The functions in many cases rely on industry-standard algorithms, as noted in the function descriptions. For more information about these algorithms, see the publicly available documentation.

Note: Compressed and encrypted data exists in a binary format that is not readable. To display this data, it must first be decompressed/decrypted to avoid output alignment problems. If table columns contain compressed or encrypted data, selects on that table must use the decompress/decrypt functions to process the binary data in those columns properly.

The following topics describe the compress and decompress, encrypt and decrypt, and uuencode and uudecode functions. These functions are inverse functions and are listed together, rather than strictly alphabetically, for ease of comparison.
