List of processBytes() Examples

Examples of processBytes()

freenet.crypt.CTRBlockCipher.processBytes()
Encrypt some data. @param input The input data array. @param offsetIn The offset within the input data array to the first byte. @param length The number of bytes to encrypt. @param output The output data array. @param offsetOut The offset within the output data array to the first byte.
org.bouncycastle.crypto.BufferedAsymmetricBlockCipher.processBytes()
add len bytes to the buffer for processing. @param in the input data @param inOff offset into the in array where the data starts @param len the length of the block to be processed.
org.bouncycastle.crypto.BufferedBlockCipher.processBytes()
process an array of bytes, producing output if necessary. @param in the input byte array. @param inOff the offset at which the input data starts. @param len the number of bytes to be copied out of the input array. @param out the space for any output that might be produced. @param outOff the offset from which the output will be copied. @return the number of output bytes copied to out. @exception DataLengthException if there isn't enough space in out. @exception IllegalStateException if the cipher isn't initialised.
org.bouncycastle.crypto.engines.RC4Engine.processBytes()
org.bouncycastle.crypto.modes.CTSBlockCipher.processBytes()
process an array of bytes, producing output if necessary. @param in the input byte array. @param inOff the offset at which the input data starts. @param len the number of bytes to be copied out of the input array. @param out the space for any output that might be produced. @param outOff the offset from which the output will be copied. @return the number of output bytes copied to out. @exception DataLengthException if there isn't enough space in out. @exception IllegalStateException if the cipher isn't initialised.
org.bouncycastle.crypto.modes.GCMBlockCipher.processBytes()
org.bouncycastle.crypto.paddings.PaddedBufferedBlockCipher.processBytes()
process an array of bytes, producing output if necessary. @param in the input byte array. @param inOff the offset at which the input data starts. @param len the number of bytes to be copied out of the input array. @param out the space for any output that might be produced. @param outOff the offset from which the output will be copied. @return the number of output bytes copied to out. @exception DataLengthException if there isn't enough space in out. @exception IllegalStateException if the cipher isn't initialised.
