decipher
fun ByteBuf.decipherRsa(exp: BigInteger, mod: BigInteger, size: Int, preferNative: Boolean = true): ByteBuf
Deciphers a slice from this buffer using RSA encryption/decryption.
Return
a slice of this buffer using this buffer's allocator that is the result of running the modPow operation on the slice.
Parameters
exp
the exponent to apply to this block of data
mod
the modulo to run against the result of that
size
the number of bytes to read from this buffer for the RSA block
prefer
whether to prefer a native, faster library for RSA. This library shows ~4.7x performance improvements, but is not supported on all platforms. Any failure to use it will turn off native support and fall back to the Java variant for the rest of the applications runtime.
Throws
mod ≤ 0 or the exponent is negative and base is not relatively prime to mod.
