cipheriv encrypt condition v10.4.28

encrypting data

In pins 3

algorithm required
value
The algorithm to use
Default aes-192-cbc
key required
value
The key used to encrypt (mostly scrypt output)
data required
value
The data to be encrypted

Out pins 4

success
condition
encrypted
value
hex output
auth tag
value
error
value
If an error occured, this pin is filled

Encrypts data into a versioned, randomized, authenticated AES envelope. CBC uses a fresh IV plus encrypt-then-MAC; GCM uses a fresh nonce. The HEX output carries the IV/nonce and authentication data, so it can be passed directly to value_cipher_decrypt. key must be hex. auth_tag remains available for GCM compatibility and is nil for CBC. An unsupported algorithm or bad key sets success false with an error code and writes no output.

A typical wiring for cipheriv encrypt: value feeds the algorithm pin; value feeds the key pin; value feeds the data pin; the success out pin feeds branch.
