# Proposed changes Issue Number: close #xxx ## Problem summary The first fix: #17420, there is a compatibility problem, So add aes/sm4 V2 function to support correct behavior. The original aes/sm4 still maintains the previous behavior. —————————————— 1. ECB algorithm, `block_encryption_mode` does not take effect, it only takes effect when init vector is provided. Solved: 192/256 supports calculation without init vector 2. For other algorithms, an error should be reported when there is no init vector Initialization Vector. The default value for the block_encryption_mode system variable is aes-128-ecb, or ECB mode, which does not require an initialization vector. The alternative permitted block encryption modes CBC, CFB1, CFB8, CFB128, and OFB all require an initialization vector.
