Arguments

key

A sodium key (i.e., generated with sodium::keygen()

Examples

# Create a new key
key <- cyphr::key_sodium(sodium::keygen())
key
#> <cyphr_key: sodium>

# With this key encrypt a string
secret <- cyphr::encrypt_string("my secret string", key)
# And decrypt it again:
cyphr::decrypt_string(secret, key)
#> [1] "my secret string"
