Search Enabled Encryption - Length Preserving Scheme

The Search Enabled Encryption - Length Preserving scheme encrypts small text content in the form of word/s. Deterministic encryption is the strength of this scheme, which always produces the same ciphertext as output for the same plain text as input. Because this scheme preserves data searchability by encrypting deterministically, some types of statistical attacks are possible.

Use Case: FirstName, LastName, City, Insurance-ID, and such attributes of an object, when you want to perform a search on these fields.

IMPORTANT: The exact expansion/contraction rates depend on the ciphertext encoding used, but in the current configuration an n-character plain text will result in a (4n/7)+6 character ciphertext.
