Encodes / decodes a character string or arbitrary R object to base64 encoding.
base64enc(x, convert = TRUE)
base64dec(x, convert = TRUE)an object.
[default TRUE] logical value whether to convert the output to a character string or keep as a raw vector. Supplying a non-logical value will error.
A raw vector or character string depending on 'convert'.
For encoding: a raw vector is encoded directly, a scalar character string is translated to raw before encoding, whilst all other objects are serialised first.
The result of encoding or decoding is always a raw vector, which is translated to a character string if 'convert' is TRUE, or returned directly if 'convert' is FALSE.
Set 'convert' to FALSE when decoding a raw vector or serialised object,
which may be further passed to unserialize.
