MongoDB\Driver\ClientEncryption::encryptExpression

Parámetros

expr

La expresión de coincidencia o agregación a cifrar. Las expresiones deben utilizar al menos uno de los operadores $gt, $gte, $lt o $lte. Se utiliza un único operador de comparación.

Un ejemplo de expresión de coincidencia admitida (aplicable a consultas y a la etapa de agregación $match) es el siguiente:

[
    '$and' => [
        [ '<field>' => [ '$gt'  => '<value1>' ] ],
        [ '<field>' => [ '$lte' => '<value2>' ] ],
    ],
]

Un ejemplo de expresión de agregación admitida es el siguiente:

[
    '$and' => [
        [ '$gte' => [ '<fieldPath>', '<value1>' ] ],
        [ '$lt'  => [ '<fieldPath>', '<value2>' ] ],
    ],
]

options

Encryption options

Option	Type	Description
algorithm	string	The encryption algorithm to be used. This option is required. Specify one of the following ClientEncryption constants: MongoDB\Driver\ClientEncryption::AEAD_AES_256_CBC_HMAC_SHA_512_DETERMINISTIC MongoDB\Driver\ClientEncryption::AEAD_AES_256_CBC_HMAC_SHA_512_RANDOM MongoDB\Driver\ClientEncryption::ALGORITHM_INDEXED MongoDB\Driver\ClientEncryption::ALGORITHM_UNINDEXED MongoDB\Driver\ClientEncryption::ALGORITHM_RANGE
contentionFactor	int	The contention factor for evaluating queries with indexed, encrypted payloads. This option only applies and may only be specified when algorithm is MongoDB\Driver\ClientEncryption::ALGORITHM_INDEXED or MongoDB\Driver\ClientEncryption::ALGORITHM_RANGE.
keyAltName	string	Identifies a key vault collection document by keyAltName. This option is mutually exclusive with keyId and exactly one is required.
keyId	MongoDB\BSON\Binary	Identifies a data key by _id. The value is a UUID (binary subtype 4). This option is mutually exclusive with keyAltName and exactly one is required.
queryType	string	The query type for evaluating queries with indexed, encrypted payloads. Specify one of the following ClientEncryption constants: MongoDB\Driver\ClientEncryption::QUERY_TYPE_EQUALITY MongoDB\Driver\ClientEncryption::QUERY_TYPE_RANGE This option only applies and may only be specified when algorithm is MongoDB\Driver\ClientEncryption::ALGORITHM_INDEXED or MongoDB\Driver\ClientEncryption::ALGORITHM_RANGE.
rangeOpts	array	Index options for a queryable encryption field supporting "range" queries. The options below must match the values set in the encryptedFields of the target collection. For double and decimal128 BSON field types, min, max, and precision must all be set, or all be unset. Range index options Option Type Description min mixed Required if precision is set. The minimum BSON value of the range. max mixed Required if precision is set. The maximum BSON value of the range. sparsity int Optional. Positive 64-bit integer. precision int Optional. Positive 32-bit integer specifying precision to use for explicit encryption. May only be set for double or decimal128 BSON field types. trimFactor int Optional. Positive 32-bit integer.
