- cipher-context-update! context blob #!optional effective-lengthprocedure
Process blob with the cipher context object blob and return the corresponding chunk of ciphertext/plaintext. This procedure may be called repeatedly to process large amounts of data, for example when encrypting/decrypting a file in 4096 byte chunks.
To process less than the full blob, pass effective-length to indicate this many bytes should be processed. Supported as of egg version 2.2.4.
