sequence

public DerWriter sequence(DerWriter derWriter)

sequence

public DerWriter sequence(byte[] bytes)

bigInteger

public void bigInteger(byte... bytes)

The integer is always considered to be positive, so if the first byte is less than 0, we pad with a zero to make it positive

Parameters:

bytes - BigInteger bytes

bigInteger

public void bigInteger(byte[] bytes,
                       int off,
                       int len)

The integer is always considered to be positive, so if the first byte is less than 0, we pad with a zero to make it positive

Parameters:

bytes - BigInteger bytes

off - Offset in bytes data

len - Number of bytes to write
