encodeStringToBase64

Encodes a String into a newly-allocated Base64 encoded String.

Arguments:

• cleanString :: pdk.core.String

Result:

• output :: pdk.core.String - A newly-allocated base 64 string

Possible exceptions

• NullPointerException - throws if the cleanString argument is NULL

---

encodeFileToBase64

Encodes a File into a newly-allocated Base64 encoded String.

Arguments:

• file :: pdk.io.File - the file to encode

Result:

• output :: pdk.core.String - A newly-allocated base 64 string

Possible exceptions

• NullPointerException - throws if the file argument is NULL

---

decodeBase64ToFile

Decodes a Base64 string into a File.

Arguments:

• fileName :: pdk.core.String

• base64String :: pdk.core.String

Result:

• output :: pdk.io.File - a file representation of a decoded base 64 string

Possible exceptions

• NullPointerException - throws if the fileName or base64String argument is NULL

---

hexStringToIntegerArray

Converts a hex string to an array of integers (each integer represents a byte).

Arguments:

• hexString :: pdk.core.String

Result:

• output :: pdk.core.Array<pdk.core.Integer>

Possible exceptions

• NullPointerException - throws if the hexString argument is NULL

---

integerArrayToHexString

Converts an array of integers (byte values) to a hex string.

Arguments:

• array :: pdk.core.Array<pdk.core.Integer>

Result:

• output :: pdk.core.String - hex string

Possible exceptions

• NullPointerException - throws if the array argument is NULL

---

asciiStringToHex

Converts an ASCII string to a hex string.

Arguments:

• asciiString :: pdk.core.String

• size :: pdk.core.Integer - size of output hex string: can be set to 0 - output hex string will have size that is required for hex representation (double ASCII string length), can be set greater than ASCII string length - output hex string will have trailing zeros up to specified size

Result:

• output :: pdk.core.String - hex string

Possible exceptions

• NullPointerException - throws if the asciiString or size argument is NULL

---

hexStringToAscii

Converts a hex string to an ASCII string.

Arguments:

• hexString :: pdk.core.String

Result:

• output :: pdk.core.String - ascii string

Possible exceptions

• NullPointerException - throws if the hexString argument is NULL

---

hexStringToByteArray

Converts a hex string to a byte array.

Arguments:

• hexString :: pdk.core.String

Result:

• output :: pdk.core.Array<pdk.core.Byte>

Possible exceptions

• NullPointerException - throws if the hexString argument is NULL

---

byteArrayToHexString

Converts a byte array to a hex string.

Arguments:

• byteArray :: pdk.core.Array<pdk.core.Byte>

Result:

• output :: pdk.core.String - hex string

Possible exceptions

• NullPointerException - throws if the byteArray argument is NULL
