IBAN 验证检查

Question

我需要使用 JavaScript 进行 IBAN 验证检查。我需要遵守的规则是：

验证 IBAN 通过将 IBAN 转换为整数并对其执行基本的 mod-97 操作（如 ISO 7064 中所述）来验证 IBAN。如果 IBAN 有效，则余数等于 1。

1. 根据国家/地区检查 IBAN 总长度是否正确。如果不是，则 IBAN 无效

2. 将四个初始字符移到字符串的末尾

3. 将字符串中的每个字母替换为两位数，从而扩展字符串，其中 A = 10, B = 11, ..., Z = 35

4. 将字符串解释为十进制整数并计算该数字除以 97 后的余数

我正在为白俄罗斯的 IBAN 执行此操作，因此它必须遵循以下格式

2C 31N -

RU12300000000000000000000000000000

如何修改以下内容以满足上述规则；

function validateIBAN(iban) {
  var newIban = iban.toUpperCase(),
    modulo = function(divident, divisor) {
      var cDivident = '';
      var cRest = '';

      for (var i in divident) {
        var cChar = divident[i];
        var cOperator = cRest + '' + cDivident + '' + cChar;

        if (cOperator < parseInt(divisor)) {
          cDivident += '' + cChar;
        } else {
          cRest = cOperator % divisor;
          if (cRest == 0) {
            cRest = '';
          }
          cDivident = '';
        }

      }
      cRest += '' + cDivident;
      if (cRest == '') {
        cRest = 0;
      }
      return cRest;
    };

  if (newIban.search(/^[A-Z]{2}/gi) < 0) {
    return false;
  }

  newIban = newIban.substring(4) + newIban.substring(0, 4);

  newIban = newIban.replace(/[A-Z]/g, function(match) {
    return match.charCodeAt(0) - 55;
  });

  return parseInt(modulo(newIban, 97), 10) === 1;
}


console.log(validateIBAN("RU1230000000000000000000000000000"));

Answer 1

您可以使用此库来验证和格式化 IBAN：https://github.com/arhs/iban.js（免责声明：我编写了该库）

但是，不支持俄罗斯和白俄罗斯，因为我在 IBAN page of wikipedia 和 official IBAN registry 上都找不到任何提及这些国家的信息，所以恐怕您必须自己修改库代码以添加它。

Answer 2

“jquery验证插件”也支持iban check：

https://github.com/jzaefferer/jquery-validation/blob/master/src/additional/iban.js

Answer 3

基于http://toms-cafe.de/iban/iban.js 的工作，我开发了我的IBAN 检查版本。

您可以通过修改变量CODE_LENGTHS来修改国家支持。

这是我的实现：

function alertValidIBAN(iban) {
    alert(isValidIBANNumber(iban));
}

/*
 * Returns 1 if the IBAN is valid 
 * Returns FALSE if the IBAN's length is not as should be (for CY the IBAN Should be 28 chars long starting with CY )
 * Returns any other number (checksum) when the IBAN is invalid (check digits do not match)
 */
function isValidIBANNumber(input) {
    var CODE_LENGTHS = {
        AD: 24, AE: 23, AT: 20, AZ: 28, BA: 20, BE: 16, BG: 22, BH: 22, BR: 29,
        CH: 21, CR: 21, CY: 28, CZ: 24, DE: 22, DK: 18, DO: 28, EE: 20, ES: 24,

        AL: 28, BY: 28, CR: 22, EG: 29, GE: 22, IQ: 23, LC: 32, SC: 31, ST: 25,
        SV: 28, TL: 23, UA: 29, VA: 22, VG: 24, XK: 20
    };
    var iban = String(input).toUpperCase().replace(/[^A-Z0-9]/g, ''), // keep only alphanumeric characters
            code = iban.match(/^([A-Z]{2})(\d{2})([A-Z\d]+)$/), // match and capture (1) the country code, (2) the check digits, and (3) the rest
            digits;
    // check syntax and length
    if (!code || iban.length !== CODE_LENGTHS[code[1]]) {
        return false;
    }
    // rearrange country code and check digits, and convert chars to ints
    digits = (code[3] + code[1] + code[2]).replace(/[A-Z]/g, function (letter) {
        return letter.charCodeAt(0) - 55;
    });
    // final check
    return mod97(digits);
}

function mod97(string) {
    var checksum = string.slice(0, 2), fragment;
    for (var offset = 2; offset < string.length; offset += 7) {
        fragment = String(checksum) + string.substring(offset, offset + 7);
        checksum = parseInt(fragment, 10) % 97;
    }
    return checksum;
}

input { width:300px; }

Enter IBAN 
<input type="test" id="iban"/>
<button onclick="alertValidIBAN(null);">check IBAN</button>

Answer 4

根据之前的答案，我创建了一个实现 Angular Validator 方法的 Directive。
我还添加了类型。

iban-validator.directive.ts

import { Validator, AbstractControl, NG_VALIDATORS } from '@angular/forms';
import { Directive } from '@angular/core';

@Directive({
  selector: '[ibanValidators]',
  providers: [{
    provide: NG_VALIDATORS,
    useExisting: IbanValidatorDirective,
    multi: true
  }]
})

export class IbanValidatorDirective implements Validator {

  validate(control: AbstractControl): object {
    const codeLengths = {
      AD: 24, AE: 23, AL: 28, AT: 20, AZ: 28, BA: 20, BE: 16, BG: 22, BH: 22, BR: 29, CH: 21, CR: 21, CY: 28, CZ: 24,
      DE: 22, DK: 18, DO: 28, EE: 20, ES: 24, LC: 30, FI: 18, FO: 18, FR: 27, GB: 22, GI: 23, GL: 18, GR: 27, GT: 28,
      HR: 21, HU: 28, IE: 22, IL: 23, IS: 26, IT: 27, JO: 30, KW: 30, KZ: 20, LB: 28, LI: 21, LT: 20, LU: 20, LV: 21,
      MC: 27, MD: 24, ME: 22, MK: 19, MR: 27, MT: 31, MU: 30, NL: 18, NO: 15, PK: 24, PL: 28, PS: 29, PT: 25, QA: 29,
      RO: 24, RS: 22, SA: 24, SE: 24, SI: 19, SK: 24, SM: 27, TN: 24, TR: 26
    };
    if (control.value) {
      const iban = control.value.toUpperCase().replace(/[^A-Z0-9]/g, '');
      const code = iban.match(/^([A-Z]{2})(\d{2})([A-Z\d]+)$/);
      let digits: number;
      if (!code || iban.length !== codeLengths[code[1]]) {
        return { ibanValid: false };
      }
      digits = (code[3] + code[1] + code[2]).replace(/[A-Z]/g, (letter: string) => {
        return letter.charCodeAt(0) - 55;
      });
      return this.mod97(digits) === 1 ? null : { ibanValid: false };
    }
  }

  private mod97(digital: number | string) {
    digital = digital.toString();
    let checksum: number | string = digital.slice(0, 2);
    let fragment = '';
    for (let offset = 2; offset < digital.length; offset += 7) {
      fragment = checksum + digital.substring(offset, offset + 7);
      checksum = parseInt(fragment, 10) % 97;
    }
    return checksum;
  }
}

然后只需在输入上使用指令。

Answer 6

我知道这是一个老话题，但由于它在 Google 上排名第一，而且这里的解决方案并没有真正完善，我想向您展示我的看法：

export const validIban = (value) => {
    let rearrange =
        value.substring(4, value.length)
        + value.substring(0, 4);
    let alphabet = "ABCDEFGHIJKLMNOPQRSTUVWXYZ".split('');
    let alphaMap = {};
    let number = [];

    alphabet.forEach((value, index) => {
        alphaMap[value] = index + 10;
    });

    rearrange.split('').forEach((value, index) => {
        number[index] = alphaMap[value] || value;
    });

    return modulo(number.join('').toString(), 97) === 1;
}

const modulo = (aNumStr, aDiv) => {
    var tmp = "";
    var i, r;
    for (i = 0; i < aNumStr.length; i++) {
        tmp += aNumStr.charAt(i);
        r = tmp % aDiv;
        tmp = r.toString();
    }
    return tmp / 1;
}

它对我来说效果很好，你可以用它来测试它 validIban(testThis) / http://randomiban.com

我已经设法创建了以下 RegEx，以便根据当前格式进行快速验证。

Answer 8

根据最新的 SWIFT IBAN Registrar 出版物（2021 年 6 月），here，我更新了 Rony Nasr 的 REGEX 提案。它包括 79 个国家/地区并检查特定国家/地区的 IBAN 结构和长度。 （但是，它不会进行校验和 MOD97 验证）。

Answer 9

我写了 2 个正则表达式，第一个适用于仅 SEPA 的国家/地区，另一个适用于所有支持 IBAN 的国家/地区，截至 2021-10。

SEPA 区域内国家/地区的 IBAN 正则表达式

第一个检查 IBAN 在 SEPA 区域内是否有效，IBAN 必须属于 SEPA 区域内的国家/地区。 （它认为 SEPA 区域之外的 IBAN 无效）

^(?:((?:IT|SM)\d{2}[A-Z]{1}\d{22})|(NL\d{2}[A-Z]{4}\d{10})|(LV\d{2}[A-Z]{4}\d{13})|((?:BG|GB|IE)\d{2}[A-Z]{4}\d{14})|(GI\d{2}[A-Z]{4}\d{15})|(RO\d{2}[A-Z]{4}\d{16})|(MT\d{2}[A-Z]{4}\d{23})|(NO\d{13})|((?:DK|FI)\d{16})|((?:SI)\d{17})|((?:AT|EE|LU|LT)\d{18})|((?:HR|LI|CH)\d{19})|((?:DE|VA)\d{20})|((?:AD|CZ|ES|MD|SK|SE)\d{22})|(PT\d{23})|((?:IS)\d{24})|((?:BE)\d{14})|((?:FR|MC|GR)\d{25})|((?:PL|HU|CY)\d{26}))$

第二个正则表达式取自 https://stackoverflow.com/a/69068004/2391795，稍作修改以添加对 GE（格鲁吉亚）国家/地区的适当支持。

只要使用这个网站的 api : 去https://api.ibanapi.com 并得到 apk_key

iban    = SA4705000068203056854000
api_key = ea649b36c1d1648bf0f12df82a8da475e2ee3447
url     = 'https://api.ibanapi.com/v1/validate/'iban+'?api_key='+api_key+''

IBAN 检查器

• 检查 IBAN 的结构并为验证引擎做好准备
• 确保该国家/地区根据 Swift 公共注册支持 IBAN
• 使用校验位验证 IBAN。
• 如果支持国家级验证，则会通过它运行
• 从我们的注册中心获取此 IBAN 的银行信息
