AcraStructs vs AcraBlocks # Acra services support two types of cryptographic containers: AcraStruct and AcraBlock. Plaintext data is encrypted using one container or another. Then, encrypted data is stored in the database and decrypted back by AcraServer/AcraTranslator when needed. Always prefer using AcraBlocks except when data is encrypted on client-side using AcraWriter. AcraStructs use asymmetric cryptography and are generally slower. Read more on When use AcraBlocks and when AcraStructs.
