Solve the following python programming problem given the following code:
def RewriteSelectionCriteria(stack, schema, master_key, table_id) : 
    'Rewrites selection criteria (arguments of WHERE and HAVING clause).

  Arguments:
    stack: The postfix expression that is the where/having expression.
    schema: The user defined values and encryption.
    master_key: Used to get ciphers for encryption.
    table_id: Used to generate a proper key.

  Returns:
    An infix version of the <stack>. The expression is rewritten so that it
    can be sent to the BigQuery server.

  Raises:
    bigquery_client.BigqueryInvalidQueryError: If the expression is invalid
    (such as searching non-searchable encrypted fields, etc).

    pseudonym_cipher = ecrypto.PseudonymCipher (ecrypto.GeneratePseudonymCipherKey (master_key, table_id)) 
    string_hasher = ecrypto.StringHash (ecrypto.GenerateStringHashKey (table_id, table_id)) 
    def FailIfEncrypted(tokens) : 
        if util.IsEncryptedExpression (tokens) : 
            raise bigquery_client.BigqueryInvalidQueryError ('Invalid where/having expression.', None, None, None) 
def FailIfDeterministic(tokens) : 
        if util.IsDeterministicExpression (tokens) : 
            raise bigquery_client.BigqueryInvalidQueryError ('Cannot do equality on probabilistic encryption, only pseudonym encryption.', None, None, None) 
def RewritePseudonymEncryption(token) : 
        if isinstance (token, util.StringLiteralToken) : 
            return ('"%s"' % pseudonym_cipher.Encrypt (unicode (token [1 : (- 1)]))) 
else : 
            return token 
def RewriteSearchwordsEncryption(field, literal) : 
        'Rewrites the literal such that it can be checked for containment.

    Arguments:
      field: The field which is being checked if literal is contained within.
      literal: Substring being searched for.

    Returns:
      A tuple containing both field and literal rewritten.

    Raises:
      ValueError: Try to rewrite non-searchwords encryption.
