| 50 <div style="margin-left: 2em; font-size: 0.75em;">OTPWCalc - Client application for calculating responses to OTP challenges.</div> | |
| 51 <div style="margin-top: 1.5em; text-transform: uppercase; font-size: 0.75em;">Synopsis</div> | |
| 52 <div style="margin-left: 2em; font-size: 0.75em;">OTPWCalc [-h] [-v] [-V]</div> | |
| 53 <div style="margin-top: 1.25em; text-transform: uppercase; font-size: 0.75em;">Description</div> | |
| 54 <div style="margin-left: 2em; font-size: 0.75em;">Playing the role of a hardware | |
| 55 token in a client server authentication system as described | |
| 56 in RFC 2289, OTPWCalc calculates responses to incoming | |
| 57 authentication challenges as typed in by the user.</div> | |
| 58 <div style="margin-top: 1.25em; text-transform: uppercase; font-size: 0.75em;">Options</div> | |
| 59 <div style="margin-left: 2em; font-size: 0.75em;"> | |
| 60 -h Display a brief help message and exit.<br /> | |
| 61 -v Print verbose text to the calling terminal.<br /> | |
| 62 -V Print the version number and exit. | |
| 63 </div> | |
| 64 <div style="margin-top: 1.25em; text-transform: uppercase; font-size: 0.75em;">Terms</div> | |
| 65 <div style="margin-left: 2em; font-size: 0.75em;">Username</div> | |
| 66 <div style="margin-left: 4em; font-size: 0.75em;"> | |
| 67 The name that the server knows. For example, 'albertc'. | |
| 68 </div> | |
| 69 <div style="margin-left: 2em; font-size: 0.75em;">Secret</div> | |
| 70 <div style="margin-left: 4em; font-size: 0.75em;"> | |
| 71 A password, usually selected by the user, that is | |
| 72 needed to gain access to the server. For example, | |
| 73 'Mysec2-pw'. | |
| 74 </div> | |
| 75 <div style="margin-left: 2em; font-size: 0.75em;">Challenge</div> | |
| 76 <div style="margin-left: 4em; font-size: 0.75em;"> | |
| 77 Information printed by the server when it tries to | |
| 78 authenticate a user. This information is needed by | |
| 79 OTPWCalc to generate a proper response. For example, | |
| 80 'otp-md5 820 dinw23612'. | |
| 81 </div> | |
| 82 <div style="margin-left: 2em; font-size: 0.75em;">Response</div> | |
| 83 <div style="margin-left: 4em; font-size: 0.75em;"> | |
| 84 Information generated from a challenge that is used | |
| 85 by the server to authenticate the user. For example, | |
| 86 'BIEM ROSE JINX HARD BALL SKY NEW'. | |
| 87 </div> | |
| 88 <div style="margin-left: 2em; font-size: 0.75em;">Seed</div> | |
| 89 <div style="margin-left: 4em; font-size: 0.75em;"> | |
| 90 Information used in conjunction with the secret and | |
| 91 sequence number to compute the response. It allows | |
| 92 the same secret to be used for multiple sequences | |
| 93 by changing the seed, or for authentication to | |
| 94 multiple servers by using different seeds. | |
| 95 </div> | |
| 96 <div style="margin-left: 2em; font-size: 0.75em;">Sequence #</div> | |
| 97 <div style="margin-left: 4em; font-size: 0.75em;"> | |
| 98 A counter used to track key iterations. Each time | |
| 99 a successful response is received by the server the | |
| 100 sequence number is decremented. For example, 71. | |
| 101 </div> | |
| 102 <div style="margin-left: 2em; font-size: 0.75em;">Hash ID</div> | |
| 103 <div style="margin-left: 4em; font-size: 0.75em;"> | |
| 104 Text that identifies the cryptographical algorithm | |
| 105 used. The valid hash identifiers are 'otpmd4' | |
| 106 corresponding to MD4, and 'otp-md5' corresponding | |
| 107 to MD5. | |
| 108 </div> | |
| 109 <div style="margin-top: 1.25em; text-transform: uppercase; font-size: 0.75em;">Files</div> | |
| 110 <div style="margin-left: 2em; font-size: 0.75em;"> | |
| 111 The application may store a cookie in a file used to | |
| 112 restore the most recent settings. The location of this | |
| 113 file (or arbitrary data structure) varies according to | |
| 114 the operating system. | |

| 120 All of the authentication strategies covered in the | |
| 121 standards implemented by this application are vulnerable | |
| 122 to man in the middle (MITM) attacks. The strategies can | |
| 123 be combined with public key logic to defeat such attacks. | |

| 127 The IETF standards RFC 1760 (The S/KEY One-Time Password | |
