simple_encryption

English | 简体中文

Encrypt data table ID on server side

Usage

Comparison value string

var contrast string = "{\"extraItem\":2,\"key\":[\"jb10=m/zkvpds=1/\",\"/*-+0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz\"]}"

• extraItem: Extra item add position, currently only supports 1 character
• key[0]: Encryption key
• key[1]: Character set used for encryption, characters not in the character set will be ignored

Initialize

• Function: New
• Parameter:
  • extraItem: Extra item add position, currently only supports 1 character
  • key: Encryption key
  • cryptKey: Character set used for encryption, characters not in the character set will be ignored
• Return value:
  • se: SimpleEncryption object
  • err: Error message
• Example:

se, err := New(extraItem, key, cryptKey)
if err != nil {
    println("encrypt error:", err)
    return
}

Initialize with Json string

• Function: NewJson
• Parameter:
  • contrast: Json string of key
• Return value:
  • se: SimpleEncryption object
  • err: Error message
• Example:

se, err := NewJson(contrast)
if err != nil {
    println("encrypt error:", err)
    return
}

encrypt

• Function: encrypt
• Parameter:
  • str: String to be encrypted
  • extra: Extra encryption item, currently only supports 1 character
• Return value:
  • enStr: Encrypted string
  • err: Error message
• Example:

var (
    extra   string = "1"
    str     string = "1z3a+bc f"
    enStr   string = ""
    err     error  = nil
)
se, err := New(contrast)
if err != nil {
    t.Error("encrypt error:", err)
    return
}
println("[extra]:  ", extra, "[str]:", str)
enStr, err = se.encrypt(str, extra)
if err != nil {
    println("encrypt error:", err)
    return
}
println("[encrypt]:         ", enStr)

• Output:

[extra]:      1 [str]:      1z3a+bc f
[encrypt]:                  ec/xLjLJ 1

decrypt

• Function: decrypt
• Parameter:
  • str: String to be decrypted
• Return value:
  • reStr: Decrypted string
  • reExtra: Extra encryption item
  • err: Error message
• Example:

var (
    str     string = "ec/xLjLJ 1"
    reStr   string = ""
    reExtra string = ""
    err     error  = nil
)
se, err := New(contrast)
if err != nil {
    println("encrypt error:", err)
    return
}
println("[str]:               ", str)
reStr, reExtra, err = se.decrypt(str)
if err != nil {
    println("decrypt error:", err)
    return
}
println("[extra]:", reExtra, "[decrypt]:", reStr)

• Output:

[str]:                ec/xLjLJ 1
[extra]: 1 [decrypt]: 1z3a+bc f
