Security Functions

Security functions provide the ability to interact with the security system or to hash/encrypt values.

HASROLE

Whether the current caller has the Teiid data role roleName.

hasRole([roleType,] roleName)

roleName must be a string, the return type is boolean.

The two argument form is provided for backwards compatibility. roleType is a string and must be `data'.

Role names are case-sensitive and only match Teiid Data Roles. JAAS roles/groups names are not valid for this function - unless there is corresponding data role with the same name.

MD5

Computes the MD5 hash of the value.

MD5(value)

value must be a string or varbinary, the return type is varbinary. String values are first converted to their UTF-8 byte representation.

SHA1

Computes the SHA-1 hash of the value.

SHA1(value)

value must be a string or varbinary, the return type is varbinary. String values are first converted to their UTF-8 byte representation.

SHA2_256

Computes the SHA-2 256 bit hash of the value.

SHA2_256(value)

value must be a string or varbinary, the return type is varbinary. String values are first converted to their UTF-8 byte representation.

SHA2_512

Computes the SHA-2 512 bit hash of the value.

SHA2_512(value)

value must be a string or varbinary, the return type is varbinary. String values are first converted to their UTF-8 byte representation.

AES_ENCRYPT

aes_encrypt(data, key)

AES_ENCRYPT() allow encryption of data using the official AES (Advanced Encryption Standard) algorithm, 16 bytes(128 bit) key length, and AES/CBC/PKCS5Padding cipher algorithm with an explicit initialization vector.

The AES_ENCRYPT() will return a BinaryType encrypted data. The argument data is a BinaryType data that need to encrypt, the argument key is a BinaryType used in encryption.

AES_DECRYPT

aes_decrypt(data, key)

AES_DECRYPT() allow decryption of data using the official AES (Advanced Encryption Standard) algorithm, 16 bytes(128 bit) key length, and AES/CBC/PKCS5Padding cipher algorithm expecting an explicit initialization vector.

The AES_DECRYPT() will return a BinaryType decrypted data. The argument data is a BinaryType data that need to decrypt, the argument key is a BinaryType used in decryption.
